Simplifying quadratic formula

WebbQuadratic Formula. The solutions to a quadratic equation of the form ax2 + bx + c = 0, a ≠ 0 are given by the formula: x = −b ± √b2 − 4ac 2a. To use the Quadratic Formula, we substitute the values of a, b, andc into the expression on the right side of the formula. Then, we do all the math to simplify the expression. WebbTo simplify an expression with fractions find a common denominator and then combine the numerators. If the numerator and denominator of the resulting fraction are both divisible by the same number, simplify the fraction by dividing both by that number. Simplify any resulting mixed numbers.
