Question

.If 2 is a zero of the polynomial p(x)=2x²-3x+7a, then find the value of a

Answer 1

Answer:

Given,

p(x) = 2x²-3x+7a

2 is the zero of the polynomial

So, substitution

p(2) = 0

p(2) = 2(2)^2 - 3x + 7a

0 = 2(4)-3(2)+7a

0 = 8-6+7a

0 = 2+7a

-2 = 7a

-2/7 = a

-2/7 = a

The value of a is -2/7

Answer 2

Ans : p(x)= 2x2 -3x+7a

p(2)=2(2)2-3(2)+7a

p(2)=8-6+7a

p(2)=2+7a

7a= -2

a = -2/7

hope it helps uh
