Choose the correct simplification of the expression (7x − 3)(4x2 − 3x − 6).
28x3 − 33x2 − 33x − 18
28x3 + 33x2 − 33x + 18
28x3 − 51x2 − 33x + 18
28x3 − 33x2 − 33x + 18

Best ResponseYou've already chosen the best response.0First work with the first term, 7x * 4x^2 and you get 28x^3. Then multiply the first term of the binomial and second term of the trinomial. so 7x * 3x what do you get? @Keigh2015

Best ResponseYou've already chosen the best response.0In this order 28x^2 21x 42x 12x^2 9x 18

Best ResponseYou've already chosen the best response.0Your right for all the ones except the first two. The numbers are right but you forgot to combine the exponents so think of x^2 * x as x^2+1 since x has the exponential value of 1. So you would get an exponential value of 3. So it would be 28x^3. And same goes for x * x so it would be x^1+1 which is 2. So it should be 21x^2. 28x^3 21x^2 42x 12x^2 9x 18 Now combine like terms (that is terms with same exponent. So what is 21x^2 + (12x^2)

Best ResponseYou've already chosen the best response.0Yes because 28x^3 is the only term with an exponential value of 3 and 21 + (12) is like 21  12 which is 33. Then you replace the x and exponential value so its 33x^2. Good job, now we can eliminate answe C since the second term is 51x^2 which is wrong. So now what is 42x + 9x?

Best ResponseYou've already chosen the best response.0By the way we can also eliminate B as well since the second term is positive and ours is negative. And yes it is 33x. Last step is to add the 18 to your equation so combine all those answers you just gave me.

Best ResponseYou've already chosen the best response.0Correct so when you look at the answers the only one that matches it is D. I hope this helped you don't forget to close this question and choose the person that was the greatest help to you by hitting best response and have a wonderful day. @Keigh2015
