Find the zero of the polynomial p(x)=x2-16 |
|
Answer» <P>Given -
To Find -
Now, → x² - 16 → (x)² - (4)²
→ (x + 4)(x - 4) Zeroes are - → x + 4 = 0 and x - 4 = 0 → x = -4 and x = 4 Verification :-
→ -4 + 4 = -(0)/1 → 0 = 0 LHS = RHS And
→ -4 × 4 = -16/1 → -16 = -16 LHS = RHS Hence, Verified... It SHOWS that our answer is ABSOLUTELY CORRECT. |

2 ] Express each of the following equations in the form ax + by + c = 0 and indicate thevalues of a, b, c in each case.(i) x = 6(ii) 3x – y = x – 1(iii) 2x + 9 = 0(iv) 4y = 7(v) x + y = 4 |
|
Answer» Step-by-step explanation: (i) x = 6 In the form of ax + by + c = 0 we have x+0y+(-6)=0 where a = 1, B = 0 and c=-6. (ii) 3X – y = x – 1 In the form of ax + by + c = 0 we have 2x+(-1y)+1=0 where a = 2, b = -1 and c = 1 (iii) 2x + 9 = 0 In the form of ax + by + c = 0 we have 2x+(-1y)+1=0 where a = 2, b = -1 and c = 1 (IV) 4y = 7 In the form of ax + by + c = 0 we have 0x+4y+(-7)=0 where a = 0, b = 4 and c = -7 (v) x + y = 4 In the form of ax + by + c = 0 we have 1x+1y+(-4)=0 where a=1,b=1,c=-4 (vi) x 2
- y 3
= 1 6
+y In the form of ax + by + c = 0 we have 3x-2y=1+6y⇒3x-8y+(-1)=0 where a=3,b=-8,c=-1. |

For what values of p and q, the expression,x⁴ - 14x³ + 71x² + px +q is a perfect square? |
|
Answer» Answer: p=-546, q=1521;;; Step-by-step explanation: let me assume that the square ROOT of the equation is a quadratic equation x^2+ax+b=0;(x^2 coefficient is 1 CUZ we can infer from the equation in the QUESTION) so (x^2+ax+b)^2=x^4-14^3+71x^2+px+q compare the coefficients after EXPANDING the equation do the math you will find a=-7 b=39 comparsion GIVES p=2ab q=b^2 so p=-546 q=1521 this m8 help:) |

Find the middle term of AP -15,-11,-7,-3...49 |
|
Answer» Answer: Ans:- 9 Step-by-step explanation: The formula of an A.P. TN = a + (n - 1)d but to find middle:- n/2 therefore: tn = a + (n - 1) X d substituting the values, 49 = -15 + (n - 1)X 4 (n - 1) = 49 + 15 / 4 n - 1 = 16 n = 17 therefore:- n is odd so middle term would be (n+1)/2 = 18/2 = 9 I HOPE this helps out . |

The sum of three consecutive even integers is 108. What is the largest number? |
Answer» Let:-The three consecutive even numbers be 2x , 2x + 2 and 2x + 4 . Given:-SUM of these three consecutive even numbers = 108 Now on adding these three consecutive even numbers we GET ,=> 2x + (2x + 2) + (2x + 4) = 108 => 2x + 2x + 2x + 2 + 4 = 108 => 6x + 6 = 108 => 6(x + 1) = 108 =>x + 1 = 18 => x = 17 On putting the value of x in 2x , 2x +2 and 2x + 4 the numbers we have, => 2x = 2×17 = 34 => 2x + 2 = 2×17 + 2 = 36 => 2x + 4 = 2×17 + 4 = 38 Therefore:-The largest number is 38. |

Discuss the movement launched by the Indian National Congress in 1942 |
|
Answer» Step-by-step explanation: On 8 August 1942 at the All-India Congress Committee session in Bombay, Mohandas Karamchand Gandhi launched the 'Quit India' movement. The next day, Gandhi, Nehru and many other leaders of the Indian National Congress were arrested by the BRITISH Government. Disorderly and non-violent demonstrations took place throughout the country in the following days. By the middle of 1942, Japanese troops were approaching the borders of India. Pressure was mounting from China, the United States and Britain to solve the issue of the future status of India before the end of the war. In March 1942, the PRIME Minister dispatched Sir Stafford Cripps, a MEMBER of the War Cabinet, to India to discuss the British Government's Draft Declaration. The draft granted India DOMINION status after the war but otherwise conceded few changes to the British Government Act of 1935. The draft was unacceptable to the Congress Working Committee who rejected it. The FAILURE of the Cripps Mission further estranged the Congress and the British Government. please mark as brainliest and follow |
