To substitute coefficients into the quadratic formula, first identify a, b, and c from the standard form ax2+bx+c=0. Replace a, b, and c in the formula x=2a−b±b2−4ac with their numerical values.
Conditions: The equation is in standard form ax2+bx+c=0.; The coefficients a, b, and c have been correctly identified.

To simplify a fraction, find a common factor for both the numerator and the denominator. Rewrite them as products including this common factor, then cancel the common factor from the top and bottom.
Conditions: The numerator and denominator must share a common factor greater than 1.; The fraction is not yet in its simplest form.
