In this case, `-1/2 × (-7/2) = 7/4`, Step 2: Expand `(7/4 − u)(7/4 + u) = 49/16 − u^2`, Step 3: Set that expansion equal to the constant term: `49/16 - u^2 = 3/2`. SOLVING QUADRATIC EQUATIONS BY FACTORING EXAMPLES WITH ANSWERS. A reader asked how to find the equation of a parabola from its graph. atOptions = { 5. Transform the equation using standard form in which one side is zero. determine. Recognize when the quadratic formula gives complex solutions and write them as ± for real numbers and . 1 k 1 k 5. The general form of a quadratic equation is. Step 5: Substitute either value (we'll use `+5/4`) into the `u` bracket expressions, giving us the same roots of the quadratic equation that we found above: How To Use the Quadratic Formula by Hector the Battle Droid, How to find the equation of a quadratic function from its graph, Equation of the axis of symmetry for a parabola? In this case, `-1/2 × (−2) = 1`, Step 2: Expand `(1 − u)(1 + u) = 1 − u^2`, Step 3: Set that expansion equal to the constant term: `1 - u^2 = -15`. Solving quadratic equations by factoring date period solve each equation by factoring. 8. A quadratic equation can also be solved by factoring, using the square roots or quadratic formula. 1. substitution. by Sharon [Solved!]. 1) k+ 1)(k− 5)= 0 2) (a+ 1)(a+ 2)= 0 3) (4k+ 5)(k+ 1)= 0 4) (2m+ 3)(4m+ 3)= 0 5) x2− 11x+ 19 = −5 6) n2+ 7n+ 15 = 5 7) n2− 10n+ 22 = −2 8) n2+ 3n− 12 = 6 9) 6n2− 18n− 18 = 6 10) 7r2− 14r= −7.
