Find the zeroes of the quadratic polynomial 6x²-3-7x and verify the relationship between the zeroes and coefficients. Explanation must ✓ Steps needed ✓ |
|
Answer» ER is attached above also Given f(x) = 6x2 – 7x – 3 To find the zeros Let us put f(x) = 0 ⇒ 6x2 – 7x – 3 = 0 ⇒ 3x(2x – 3) + 1(2x – 3) = 0 ⇒ (2x – 3)(3x + 1) = 0 ⇒ 2x – 3 = 0 x = 3/2 ⇒ 3x + 1 = 0 ⇒ x = -1/3 It gives us 2 zeros, for x = 3/2 and x = -1/3 Hence, the zeros of the quadratic equation are 3/2 and -1/3. Now, for verification Sum of zeros = – coefficient of x / coefficient of x2 3/2 + (-1/3) = – (-7) / 6 7/6 = 7/6 Product of roots = constant / coefficient of x2 3/2 x (-1/3) = (-3) / 6 -1/2 = -1/2 Therefore, the relationship between zeros and their coefficients is VERIFIED. |

In a four digit number, the sum of the first two digits is equal to that of the last two digits. The sum of the first and last digits is equal to the third digit. Finally, the sum of the second and fourth digits is twice the sum of the other two digits. What is the third digit of the number? |
|
Answer» ong>Answer: Let the 1ST, 2nd, 3rd and 4th digits be a,b,c and d respectively. So, four-DIGIT no. will be dcba → ACCORDING to the given question, ⇒ a+b=c+d --- ( 1 ) ⇒ a+d=c --- ( 2 ) ⇒ b+d=2(a+c) ---- ( 3 ) ∴ a+b=a+2d [ SUBSTITUTING value of equation ( 2 ) in equation ( 1 ) ] ∴ b=2d --- ( 4 ) ⇒ 2d+d=2(a+a+d) [ Substituting EQ ( 4 ) and ( 2 ) in eq. ( 3 ) ] ∴ d=4a or a= 4 d
--- ( 5 ) ⇒ 4 d
+d=c --- [Substituting ( 5 ) in ( 2 ) ] ∴ c= 4 5d
or c= 4d 5
Now d=4a Since a and d are single digits and we have to form 4 digit no. a<10 and 0 So, the possible integer values of a and d which satisfy d=4a are 1.a=1,d=4 2.a=2,d=8 ∴ The value of d can be either 4 or 8 ⇒ When d=4, then c=5. ⇒ When d=8, then c=10. ⇒ But the value of c should be less than 10 as it is a single digit. ∴ Value of c would be 5 which is the third digit of the required number. |
