Question

Factors of the polynomial 3 X square + 4 x minus 7

Answer 1

Step-by-step explanation:

let p(x) = 3x^2 + 4x -7

The constant term is (7) here,

The factors of 7 = -1 , +1 ,-7 ,+7.

now at the place of p(x) put the factors of 7 and see whether the ans. = 0 or not.

p(1)= 3(1^2) + 4(1) -7

= 3+4-7

p(1)= 7-7 =0 .

(x +1) is a factor of 3x^2 + 4x +7.
