How to solve square root quadratic equations
WebCompleting the square works as long as we can divide by 2. So as long as we can divide by 2 and take square roots, the quadratic formula gives the roots of the equation. If the modulus is odd (as in your case), we can always divide by 2. Whether taking a (modular) square root is possible will depend on the precise equation. WebFinding Roots of Quadratic Equation by Quadratic Formula Find a, b, and c values by comparing the given equation with ax 2 + bx + c = 0. Then a = 1, b = -7 and c = 10 Substitute them in the quadratic formula and simplify. x = [- (-7) ± √ ( (-7) 2 - 4 (1) (10))] / (2 (1)) = [ 7 ± √ (49 - 40) ] / 2 = [ 7 ± √ (9) ] / 2 = [ 7 ± 3 ] / 2
