So, the root of corresponding quadratic equation is 0. check by substituting x = 0 into x2 = 0. left side right side x2 0 = 02 = 0 the solution is correct. b) the x intercepts of the graph in #1 b) are –4 and –1. so, the roots of corresponding quadratic equation are –4 and –1. check by substituting x = –4 and x = –1 into –x2. This video includes a detailed explanation of 1) complex numbers & quadratic equations (introduction, complex numbers, algebra of complex numbers, the modulu. A quadratic equation in the variable x is an equation of the form ax2 bx c = 0, where a, b, c are real numbers, a 0. for example, 2x2 x – 300 = 0 is a quadratic equation. ≠ similarly, 2x2 – 3x 1 = 0, 4x – 3x2 2 = 0 and 1 – x2 300 = 0 are also quadratic equations. in fact, any equation of the form p(x) = 0, where p(x) is a.
