2x^{2}-3x-2x=-2x^{2}
Subtract 2x from both sides.
2x^{2}-5x=-2x^{2}
Combine -3x and -2x to get -5x.
2x^{2}-5x+2x^{2}=0
Add 2x^{2} to both sides.
4x^{2}-5x=0
Combine 2x^{2} and 2x^{2} to get 4x^{2}.
x\left(4x-5\right)=0
Factor out x.
x=0 x=\frac{5}{4}
To find equation solutions, solve x=0 and 4x-5=0.
2x^{2}-3x-2x=-2x^{2}
Subtract 2x from both sides.
2x^{2}-5x=-2x^{2}
Combine -3x and -2x to get -5x.
2x^{2}-5x+2x^{2}=0
Add 2x^{2} to both sides.
4x^{2}-5x=0
Combine 2x^{2} and 2x^{2} to get 4x^{2}.
x=\frac{-\left(-5\right)±\sqrt{\left(-5\right)^{2}}}{2\times 4}
This equation is in standard form: ax^{2}+bx+c=0. Substitute 4 for a, -5 for b, and 0 for c in the quadratic formula, \frac{-b±\sqrt{b^{2}-4ac}}{2a}.
x=\frac{-\left(-5\right)±5}{2\times 4}
Take the square root of \left(-5\right)^{2}.
x=\frac{5±5}{2\times 4}
The opposite of -5 is 5.
x=\frac{5±5}{8}
Multiply 2 times 4.
x=\frac{10}{8}
Now solve the equation x=\frac{5±5}{8} when ± is plus. Add 5 to 5.
x=\frac{5}{4}
Reduce the fraction \frac{10}{8} to lowest terms by extracting and canceling out 2.
x=\frac{0}{8}
Now solve the equation x=\frac{5±5}{8} when ± is minus. Subtract 5 from 5.
x=0
Divide 0 by 8.
x=\frac{5}{4} x=0
The equation is now solved.
2x^{2}-3x-2x=-2x^{2}
Subtract 2x from both sides.
2x^{2}-5x=-2x^{2}
Combine -3x and -2x to get -5x.
2x^{2}-5x+2x^{2}=0
Add 2x^{2} to both sides.
4x^{2}-5x=0
Combine 2x^{2} and 2x^{2} to get 4x^{2}.
\frac{4x^{2}-5x}{4}=\frac{0}{4}
Divide both sides by 4.
x^{2}-\frac{5}{4}x=\frac{0}{4}
Dividing by 4 undoes the multiplication by 4.
x^{2}-\frac{5}{4}x=0
Divide 0 by 4.
x^{2}-\frac{5}{4}x+\left(-\frac{5}{8}\right)^{2}=\left(-\frac{5}{8}\right)^{2}
Divide -\frac{5}{4}, the coefficient of the x term, by 2 to get -\frac{5}{8}. Then add the square of -\frac{5}{8} to both sides of the equation. This step makes the left hand side of the equation a perfect square.
x^{2}-\frac{5}{4}x+\frac{25}{64}=\frac{25}{64}
Square -\frac{5}{8} by squaring both the numerator and the denominator of the fraction.
\left(x-\frac{5}{8}\right)^{2}=\frac{25}{64}
Factor x^{2}-\frac{5}{4}x+\frac{25}{64}. In general, when x^{2}+bx+c is a perfect square, it can always be factored as \left(x+\frac{b}{2}\right)^{2}.
\sqrt{\left(x-\frac{5}{8}\right)^{2}}=\sqrt{\frac{25}{64}}
Take the square root of both sides of the equation.
x-\frac{5}{8}=\frac{5}{8} x-\frac{5}{8}=-\frac{5}{8}
Simplify.
x=\frac{5}{4} x=0
Add \frac{5}{8} to both sides of the equation.
