WebWhen the number has a negative exponent, you put that number at the denominator. For example, 1^-1 will be 1/1^1. The exponent is now positive because it was moved down to the denominator. Same thing if there is a negative power on the bottom of the fraction. 1/2^-2 is 4. 2^2 is 4, but the power is negative so I had to move it to the top. WebIn algebra, a quadratic equation (from Latin quadratus 'square') is any equation that can be rearranged in standard form as where x represents an unknown value, and a, b, and c …
