Question

F(x)=2x+6

Answer 1

Answer:

The Correct option is B. B.-10x^2-48x-54

Therefore the product of f and g. is

$F(x)\times G(x)=-10x^{2}-48x-54$

Step-by-step explanation:

Given:

F(x)=2x+6

G(x)=-5x-9

To Find:

The product of f and g.

F(x) × G(x) = ?

Solution:

The product of f and g.

$F(x)\times G(x)=(2x+6)(-5x-9)$

Applying Distributive Property we get

$F(x)\times G(x)=(2x(-5x-9)+6(-5x-9)\\=-10x^{2}-18x-30x-54$

Combining like terms we get

$F(x)\times G(x)=-10x^{2}-48x-54$

Therefore the product of f and g. is

$F(x)\times G(x)=-10x^{2}-48x-54$
