Question

Find the product of( x-3) (x+5)

Answer 1

(x-3)(x-5)

x2-15-3x+5x

x2+5x-3x-15

x(x+5)-3(x+5)

x=3 or -5

Answer 2

Given:

Two variable expressions are (x-3), (x+5)

To find:

The product of (x-3) and (x+5)

Solution:

We can find the product by following the given steps-

We know that the product of two monomials will give a binomial.

The degree of a binomial is 2.

The product= (x-3)×(x+5)

=x(x+5)-3(x+5)

=(x²+5x)-(3x+15)

= x²+5x-3x-15

= x²+2x-15

Therefore, the product of (x-3)(x+5) is x²+2x-15.
