Simplify the following polynomial expression? (5x^4-9x^3+7x-1)+(-8x^4+4x^2-3x+2)-(-4x^3+5x-1)(2x-7)
Gemiola [76]

Simplify the following polynomial expression:

(5x^4 - 9x^3 + 7x -1) + ( -8x^4 + 4x^2 - 3x + 2) - ( -4x^3 + 5x -1) (2x - 7)

Lets Simplify Your Equation, Step by Step:

(5x^4 - 9x^3 + 7x -1) + ( -8x^4 + 4x^2 - 3x + 2) - ( -4x^3 + 5x -1) (2x - 7)

Solution: ===> 5x^4 − 37x^3 − 6x^2 + 41x − 6 = 0

Distribute:

= 5x^4 + -9x^3 +7x + −1 + −8x^4 + 4x^2 + −3x + 2 + 8x^4 + −28x^3 + −10x^2 + 37x + −7

Combine Like Terms:

= 5x^4 + −9x^3 +7x + −1 + −8x^4 + 4x^2 + −3x + 2 + 8x^4 + −28x^3 + −10x^2 + 37x + −7

= (5x^4 + −8x^4 +8x^4) + (−9x^3 + −28x^3) +(4x^2+ −10x^2) +(7x + −3x + 37x)+(−1 + 2 + −7)

= 5x^4 + −37x^3 + −6x^2 + 41x + − 6

Hence, Answer:

= 5x^4 −37x^3 −6x^2 + 41x − 6 = 0

Hope that helps!!!! : )

Eddy remembers that the number of a student who liked vanilla was 1/5 of the number who liked almond
anzhelika [568]
I don't really understand this question. But I'll do my best to answer it.
So say that one student liked vanilla, and that student was 1/5 out of kids who liked almond. If that student was the only one out of five students that didn't like vanilla and liked almond, then four more students liked almond, and that one student was left out. So Eddy was right??????

Again, I don't understand what answer you want. Sorry. :/
