Question

simplify and write in standard form
(2x^2-6X-5)(3-x)

Answer 1

@keegq ,apply the distributive property.
(3)(2x^2-6X-5) - (x)(2x^2-6X-5)
now open up the brackets and simplify

Answer 2

6x^2-18x-15-2x^2+6x^2+5x

Answer 3

keegq, check again . is it -2x^2 ??

Answer 4

+2x^2

Answer 5

@keegq I meant check the power of x in 2x^2. It is wrong

Answer 6

2x^3

Answer 7

@keegq . Yes it should be
6x^2-18x-15-2x^3+6x^2+5x

Now add up all the x^2 terms and x terms separately and tell me what you get

Answer 8

2x^3+12x^2-13x-15

Answer 9

Almost right. Check the sign of 2x^3 term. It should be -2x^3

So your answer should be
-2x^3+12x^2-13x-15
