How do you factor 5x^2 = 10x

denis-greek [22]

$5x^2 = 10x$

$5x^2-10x=10x-10x$

$5x^2-10x=0$

Use quadratic formula

$\quad x_{1,\:2}=\dfrac{-b\pm \sqrt{b^2-4ac}}{2a}$

$\mathrm{For\:}\quad a=5,\:b=-10,\:c=0:\quad x_{1,\:2}=\dfrac{-\left(-10\right)\pm \sqrt{\left(-10\right)^2-4\cdot \:5\cdot \:0}}{2\cdot \:5}$

$x=\dfrac{-\left(-10\right)+\sqrt{\left(-10\right)^2-4\cdot \:5\cdot \:0}}{2\cdot \:5}:\quad 2$

$x=\dfrac{-\left(-10\right)-\sqrt{\left(-10\right)^2-4\cdot \:5\cdot \:0}}{2\cdot \:5}:\quad 0$

$x=2,\:x=0$

$\frac{740ft*1in}{8ft}=92,5in$

$\frac{800ft*1in}{8ft}=100in$
