#### Work Step by Step

To write a quadratic equation in standard form all terms must be on the same side and be equal to 0. For this example you would start by subtracting 30x from both sides. This would result in 9x$^2$-30x=-25. Next you would add 25 to both sides resulting in the equation 9x$^2$-30x+25=0. By this process the equation is now in the standard form of ax$^2$+bx+c=0.
