WebbImaginary Numbers From The Quadratic Formula When solving a quadratic equation of the form ax2 + bx + c = 0 with real coefficients a, b, c, (a not equal to zero), we can solve using the quadratic formula, given by The quadratic formula yields complex solutions when the discriminant (the expression under the radical) is negative. 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. simplify-calculator. en
