Question

Shenika factored the polynomial completely. what is the value of a? 5x3 35x2 6x 42 (5x2 a)(x b) 1 5 6 7

Answer 1

Factorising the polynomial 5x³ + 35x² + 6x + 42, the value of A is 6.

Factorisation of polynomial

Factorising a polynomial simply means to decompose the polynomial into a product of two or more polynomials.

Therefore, let's factorise 5x³ + 35x² + 6x + 42 and find the value of A

(5x² + A)(x + B)

Therefore,

5x³ + 35x² + 6x + 42

5x³ + 6x  + 35x² + 42

x(5x² + 6) + 7(5x² + 6)

Therefore,

(5x² + 6)(x + 7)

Therefore, the value of A is 6
