Exercise 50 Page 27

Apply the Distributive Property.

B

Practice makes perfect

We want to simplify the expression by finding the product of the binomials. To do so, we will apply the Distributive Property.

(2x-5)(3x+4)

Distribute (3x+4)

2x(3x+4)-5(3x+4)

Distribute 2x

6x^2+8x-5(3x+4)

Distribute -5

6x^2+8x-15x-20

Subtract term

6x^2-7x-20

We found that the product of 2x-5 and 3x+4 is 6x^2-7x-20. This corresponds to option B.
