Opening Go to : and complete the problems on the applet. Write in your answers here as an expression with a binomial square: each function in vertex form, and identify its vertex. 1. f(x) = x2 6x - 2 2. f(x) = x2 4x + 1 – – 3. h(x) = -3x2 + 18x + 30 4. f (x) = -2x2 16x + 4 – Solve by factoring. 1. x2 40 = 3x 2. 2x2 + x = 15 3. 6x2 11x = 7 – – When completing the square to solve a quadratic equation, use the following steps: Step 1: Divide all terms by a, the coefficient of x2. Step 2: Move the constant over to the other side (isolate the constant)
