Answer 2

The product of (x - 4)(x + 5) = (x² + x - 20)

GIVEN:- (x - 4) (x + 5)

TO FIND:- the product of the given

SOLUTION:-

• The product of two numbers or variables is the multiplication of times of the two numbers or variables.

According to the question,

$(x - 4) (x + 5)$

We'll multiply x and -4 with each number and variable from the other factor.

$= x(x + 5) - 4(x + 5) \\ = {x}^{2} + 5x - 4x - 20$

Subtracting the coefficient of x

$= {x}^{2} + x - 20$

Hence, the product of (x - 4)(x + 5) = (x² + x - 20)
