Answer:
-3x^4 - 13x^3 + 14x - 7
Step-by-step explanation:
(5x^4 – 9x^3 + 7x – 1) + (-8x^4 + 4x^2 – 3x + 2) - (-4x^3 + 5x - 1)(2x – 7)
simplify multiplied terms
(-4x^3 + 5x - 1)(2x – 7)
(-4x^3+10x-8)
group like terms together
(5x^4-8x^4) + (-9x^3-4x^3) + (7x-3x+10x) + (-1+2-8)
simplify grouped terms
-3x^4 - 13x^3 + 14x - 7
Answer:
x+1
Step-by-step explanation:
1.) -2(-x-1)-(x+1)
2.) -2(-x-1) = 2x+2
3.) 2x+2-(x+1)
4.) -(x+1) = -x-1
5.) 2x+2-x-1 = x+1
ANSWER: x+1
