Evaluate
5x2−x2
Collect like terms by calculating the sum or difference of their coefficients
(5−1)x2
Subtract the numbers
4x2
4x2−7x3=0
Factor the expression
x2(4−7x)=0
Separate the equation into 2 possible cases
x2=04−7x=0
The only way a power can be 0 is when the base equals 0
x=04−7x=0
Solve the equation
More Steps

Evaluate
4−7x=0
Move the constant to the right-hand side and change its sign
−7x=0−4
Removing 0 doesn't change the value,so remove it from the expression
−7x=−4
Change the signs on both sides of the equation
7x=4
Divide both sides
77x=74
Divide the numbers
x=74
x=0x=74
Solution
x1=0,x2=74
Alternative Form
