Question
Simplify the expression
Solution
x8−6x9+15x10−20x11+15x12−6x13+x14
Evaluate
x8(1−x)6
Expand the expression
x8(1−6x+15x2−20x3+15x4−6x5+x6)
Apply the distributive property
x8×1−x8×6x+x8×15x2−x8×20x3+x8×15x4−x8×6x5+x8×x6
Any expression multiplied by 1 remains the same
x8−x8×6x+x8×15x2−x8×20x3+x8×15x4−x8×6x5+x8×x6

Find the roots
Find the roots of the algebra expression
x1=0,x2=1
Evaluate
x8(1−x)6
To find the roots of the expression,set the expression equal to 0
x8(1−x)6=0
Separate the equation into 2 possible cases
x8=0(1−x)6=0
The only way a power can be 0 is when the base equals 0
x=0(1−x)6=0
Solve the equation
More Steps

Evaluate
(1−x)6=0
The only way a power can be 0 is when the base equals 0
1−x=0
Move the constant to the right-hand side and change its sign
−x=0−1
Removing 0 doesn't change the value,so remove it from the expression
−x=−1
Change the signs on both sides of the equation
x=1
x=0x=1
Solution
x1=0,x2=1
