Multiply the terms
7x−20×10x
Multiply the terms
7×10(x−20)x
Multiply the terms
7×10x(x−20)
Multiply the terms
70x(x−20)
70x(x−20)×4x−10
Multiply the terms
70×4x(x−20)(x−10)
Multiply the terms
280x(x−20)(x−10)
280x(x−20)(x−10)=0
Simplify
x(x−20)(x−10)=0
Separate the equation into 3 possible cases
x=0x−20=0x−10=0
Solve the equation
More Steps

Evaluate
x−20=0
Move the constant to the right-hand side and change its sign
x=0+20
Removing 0 doesn't change the value,so remove it from the expression
x=20
x=0x=20x−10=0
