Question

Simplify the polynomial expressions by combining like terms, and then multiply the resulting binomial expressions to find their product

(8x-9-2x)(15+5x-5)

Answer 1

`30x^(2)+15x -90`

Explanation:

Given,

⇒ (8x -9 -2x)(15 + 5x -5)

⇒ (6x -9)(10 + 5x)

⇒
`60x+30x^(2) -90-45x`

⇒
`30x^(2)+15x -90`
