What is the product? (x-5)(2x+3x-1)

Firlakuza [10]

I assume the first term of the trinomial is 2x^2, and you left out the exponent.

Multiply each term of the binomial by each term of the trinomial.
Then collect like terms.

$(x - 5)(2x^2 + 3x - 1) =$

$= x * 2x^2 + x * 3x + x * (-1) - 5 * 2x^2 - 5 * 3x - 5 * (-1)$

$= 2x^3 + 3x^2 - x - 10x^2 - 15x + 5$

$= 2x^3 - 7x^2 - 16x + 5$
