(x - x_1) (x - x_2) = 0 {/eq} Which allows us to rewrite this equation in a standard form using the FOIL method: {eq}a\left(x^2 - (x_1 + x_2)x + x_1x_2\right) = 0 {/eq} Answer and Explanation:1 Given our quadratic...
The general quadratic equation in one variable is ax2 + bx + c = 0, in which a, b, and c are arbitrary constants (or parameters) and a is not equal to 0. Such an equation has two roots (not necessarily distinct), as given by the quadratic formula x = − b ± b 2 − 4...
