http://content.nroc.org/DevelopmentalMath/U12L3T1_RESOURCE/text.html WebThe quadratic formula is used to find solutions of quadratic equations. If ax 2 + bx + c = 0, then solution can be evaluated using the formula given below; x = − b ± b 2 − 4 a c 2 a Thus, the formula will result in two solutions here. x 1 = − b − b 2 − 4 a c 2 a or x 2 = − b + b 2 − 4 a c 2 a Here, b 2 – 4ac is the discriminant (D). D = b 2 – 4ac
