How do you factor a quadratic expression
WebExample 1: Solving A Quadratic Equation By Factoring Consider the following quadratic equation: x2 – 16 = 0 We can see that the left side is a difference of squares: x 2 – 4 2 . Remember that the formula to factor a difference of squares is: A2 – B2 = (A + B) (A – B) Using this formula here with A = x and B = 4, we get: A2 – B2 = (A + B) (A – B) WebSep 4, 2024 · Factoring Method. Set the equation equal to zero, that is, get all the nonzero terms on one side of the equal sign and 0 on the other. \(ax^2 + bx + c = 0\) Factor the quadratic expression. \(()() = 0\) By the zero-factor property, at least one of the factors must be zero, so, set each of the factors equal to 0 and solve for the variable.
