x=\frac{0±\sqrt{0^{2}-4\left(-64\right)}}{2} This equation is in standard form: ax^{2}+bx+c=0. Substitute 1 for a, 0 for b, and -64 for c in the quadratic formula, \frac{-b±\sqrt{b^{2}-4ac}}{2a}.

Subtract 64 64 from both sides of the equation. x2 − 64 = 0 x 2 - 64 = 0. Use the quadratic formula to find the solutions. −b±√b2 −4(ac) 2a - b ± b 2 - 4 (a c) 2 a. Substitute the values a = 1 a = 1, b = 0 b = 0, and c = −64 c = - 64 into the quadratic formula and solve for x x. 0±√02 −4⋅(1 ⋅−64) 2⋅1 0 ± 0 2 - 4 ⋅ (1 ⋅ - 64) 2 ⋅ 1. Simplify.

2016年7月20日 · To solve the equation x 2 = 64, we need to find the value(s) of x. Here are the steps to follow: Recognize that the equation x 2 = 64 is a quadratic equation. To isolate x, we take the square root of both sides. The square root of x 2 is ∣ x ∣, which means x can be either positive or negative. The square root of 64 is 8. Therefore, we have ...
