Question

Simplify each of the following: –3x(2x + 11) - (3x - 5)(2x - 11) + 13x(2x + 5)​

Answer 1

Let's simplify step-by-step.

$\sf➛(−3x)(2x+11)−(3x−5)(2x−11)+13x(2x+5)$

Distribute:

$\sf➛=(−3x)(2x)+(−3x)(11)+−6x^2+43x+−55+(13x)(2x)+(13x)(5)$

$\sf➛=−6x^2+−33x+−6x^2+43x+−55+26x^2+65x$

Combine Like Terms:

$\sf➛=−6x^2+−33x+−6x^2+43x+−55+26x^2+65x$

$\sf ➛ = (−6x^2+−6x^2+26x^2)+(−33x+43x+65x)+(−55)$

$\sf➛ =14x^2+75x+−55$

Answer:

$\sf⇾ =14x²+75x−55$
