Solving Quadratic Equations By Square Roots Algebra Ii Khan Academy Zero product property. completing the square. solving quadratics by completing the square. solving quadratics by factoring. solving quadratics by factoring: leading coefficient ≠ 1. solving quadratics using structure. quadratics by factoring (intro) solving quadratics by factoring. the quadratic formula. So we're left with x squared is equal to 36. and then to solve for x, we can take the positive, the plus or minus square root of both sides. so we could say the plus or let me write it this way if we take the square root of both sides, we would get x is equal to the plus or minus square root of 36, which is equal to plus or minus 6. Solving quadratics by completing the square. solving quadratics by factoring. solving quadratics by factoring: leading coefficient ≠ 1. solving quadratics using structure. quadratics by factoring (intro) solving quadratics by factoring. the quadratic formula. understanding the quadratic formula. using the quadratic formula. You can eliminate the fraction by multiply by 2. since the problem will be easier to solve if x^2 is positve, change that to multiply by 2 to change the signs at the sam time. your new equation is: 100 x^2 = 46 i would use square root method to solve. add 100 to both sides take the square root of both sides. hope this helps.
