Question
Simplify the expression
2y5−10y4+20y3−20y2+10y−2
Evaluate
(y−1)3×2(y−1)2
Multiply the terms with the same base by adding their exponents
(y−1)3+2×2
Add the numbers
(y−1)5×2
Use the commutative property to reorder the terms
2(y−1)5
Expand the expression
2(y5−5y4+10y3−10y2+5y−1)
Apply the distributive property
2y5−2×5y4+2×10y3−2×10y2+2×5y−2×1
Multiply the numbers
2y5−10y4+2×10y3−2×10y2+2×5y−2×1
Multiply the numbers
2y5−10y4+20y3−2×10y2+2×5y−2×1
Multiply the numbers
2y5−10y4+20y3−20y2+2×5y−2×1
Multiply the numbers
2y5−10y4+20y3−20y2+10y−2×1
Solution
2y5−10y4+20y3−20y2+10y−2

Multiply the terms
(y−1)3×2(y−1)2
Multiply the terms with the same base by adding their exponents
(y−1)3+2×2
Add the numbers
(y−1)5×2
Use the commutative property to reorder the terms
2(y−1)5
2(y−1)5=0
Rewrite the expression
(y−1)5=0
The only way a power can be 0 is when the base equals 0
y−1=0
Move the constant to the right-hand side and change its sign
y=0+1
Solution
y=1
