Given the trinomial, what is the value of the coefficient 'b' in the factored form? (2 points) 2x2 − 12xy − 32y2 = 2(x − 8y)(x + by)

2x^2 − 12xy − 32y^2

= 2(x^2 - 6xy - 16y^2)

= 2(x - 8y)(x + 2y)

Answer

B = 2

The value of B is 2.

Step-by-step explanation:

The given trinomial is

Taking out the GCF.

The middle term can be written as -8xy+2xy.

The factored form of the given trinomial is 2(x-8y)(x+2y). The given factored form of the trinomial is 2(x − 8y)(x + By). Equate both factored form.

On comparing both the sides we get

Therefore the value of B is 2.
