Find the quadratic polynomial the sum and product of two zeros are -8/3 and 4/3 hence find the zeros of the polynomial

Answer»

Answer:

α + β = -b / a = -8 / 3

α * β = C / a = 4 / 3

a = 3

b = 8

c = 4

so the quadratic polynomial with the ZEROS -8/3 and 4/3 is 3x2 + 8x + 4

Q3} Verify that : a) -1/2+[(-4/3)+3/7]and [(-1/2)+3/7]+(-4/3) are there same .

Answer»

ANSWER:

-1/2+[(-4/3+3/7]=[(-1/2)+3/7]+(-4/3)

-1/2+[(-28/21+9/21)] = [-7/14+6/14] +(-4/3)

-1/2+[-19/21] = [-1/14]+(-4/3)

-1/2-19/21 = -1/14-4/3

18.

3y/3-5x/3=-2 and y/2+x/3=13/16

Answer»

$\huge\underline{ \underline{ \bf{ \blue{ \: solution \: : = }}}}$

$\bf \frac{3y}{3} - \frac{5x}{3} = - 2$

$\bf \frac{y}{2} + \frac{x}{3} = \frac{13}{16}$

$\bf- 5x + 3y = - 6..............(1) \\ \bf \: 16x + 24y = 39...............(2)$

Multiply both sides of the equation by -8

$\bf40x - 24y = 48 \\ \bf16x + 24y = 39$

_______________________

$\bf 56x \: \:\: \: \: \: = 87$

$\boxed{ \fbox{ \purple{x = \frac{87}{56} }}}$

Substituting. the GIVEN value of x into the equation -5x+3y=-6

$\bf - 5 \times \frac{87}{56} + 3y = - 6$

$\bf{ \boxed{ \fbox{ \purple{y = \frac{33}{56} }}}}$

Find the ratio in which a straight lines 5x-6y 21 = 0 divides the line segment joining the points(4,-1)and (2,1)

Answer»

Answer:

By MID point FORMULA

(x2+X/2)(y2+y/2)

2+4/2;1+-1/2

6/2;0/2

3;0=P

P(x,y)=mx2+m2x/m+m2, my2+M2Y1/m+m2

P(3,0)=K(2)+1(4)/K+1,K(1)+1(-1)/K+1

P(3,0)=2K+4/K+1,K-1/K+1

3=(2K+4)/K+1

3(K+1)=2K+4

3k+3=2k+4

3k-2k=4-3

k=1/1

k=1:1.........Answer
