Multiplying 3x² by 4x³ results in 12x⁵ since we multiply the coefficients 3 and 4, and add the exponents x² and x³. Similarly, multiplying 3x² by -2x² gives us -6x⁴, as we multiply -2 and 3, and add the exponents x² and x². Algebra. Find the Roots (Zeros) y=2x^2-7x-4. y = 2x2 - 7x - 4. Set 2x2 - 7x - 4 equal to 0. 2x2 - 7x - 4 = 0. Solve for x. Tap for more steps... x = - 1 2, 4. Aug 8, 2017 · The quadratic equations that has real number solutions are 0 = 4x^2 – 3x – 1, 0 = x^2 – 2x – 8 and 2x^2 – 7x – 9. Discriminant. The formula for finding the discriminant is .
