Answer 2

Answer:

How to solve your problem

(²−2+1)−1(²−2+8)

(y^{2}-2y+1)-1(y^{2}-2y+8)

(y2−2y+1)−1(y2−2y+8)

Simplify

1 Distribute

(²−2+1)−(²−2+8)

(y^{2}-2y+1)-\left(y^{2}-2y+8\right)

(y2−2y+1)−(y2−2y+8)

(²−2+1)−²+2−8

(y^{2}-2y+1)-y^{2}+2y-8

(y2−2y+1)−y2+2y−8

2Eliminate redundant parentheses

(²−2+1)−2+2−8

(y^{2}-2y+1)-y^{2}+2y-8

(y2−2y+1)−y2+2y−8

²−2+1−2+2−8

y^{2}-2y+1-y^{2}+2y-8

y2−2y+1−y2+2y−8

3 Subtract the numbers

²−2+1−2+2−8

y^{2}-2y+{\color{#c92786}{1}}-y^{2}+2y{\color{#c92786}{-8}}

y²−2y+1−y²+2y−8

²−2−7−²+2

y^{2}-2y{\color{#c92786}{-7}}-y^{2}+2y

y2−2y−7−y2+2y

4Combine like terms

²−2−7−²+2

y^{2}{\color{#c92786}{-2y}}-7-y^{2}+{\color{#c92786}{2y}}

y2−2y−7−y2+2y

²−7−²

y^{2}{-7}}-y^{2}

y2−7−y²

5Rearrange terms

²−7−²

{y^{2}-7-y^{2}

y²−7−y²

²−²−7
