Question

Zeros of the polynomial p x is equal to 2 x square - 9 is equal to 3 x are?

Answer 1

p(x) = 2x²-9 = 3x

p(x) = 2x²-9-3x = 0

p(x) = 2x²-9-x = 0/3

p(x) = 2x²-9-x = 0

p(x) = x²- 9-x = 0/2

p(x) = x² = 9

p(x) = x = √9

p(x) = x = 3 ans.

for checking the value :-

=2(3)²-9-3×3 = 0

=(2×9)-9-9. = 0

=18 - 18. = 0

0. = 0 (verified)

hence,zero of the polynomial = 3
