4) Fill in the blanks to Show each main idea. Main Idea: If a quadratic equaon is not in standard form, you can use algebra to change it to standard form. Then use factors and the zero uroduct rule to solve it. Not Standard Form Standard Form: ax: + bx + c = 0 (X+3)2+4x:0 ; Main Idea: If a quadratic equaon is a perfect square trinoruial not equal to zero, it can be easier to solve if it is not in standard form. How to Solve a Perfect Square Trinuruial Equation Step 1. Factor the perfect square triuomial. 2. Take the square root of both sides. 3. Simplify the resulting equations. 4. Solve both simplied equations
