If a polynomial function has integer coefficients, then every rational zero will have the form where is a factor of the constant and is a factor of the leading coefficient. 2x2 −6x−x+3 = 0.09.94 or 1. Add 4 4 to both sides of the equation. Factor. Multiplying 3x² by 4x³ results in 12x⁵ since we multiply the coefficients 3 and 4, and add the exponents x² and x³. x = 1/2 or x = -4. View solution steps. Use the quadratic formula to find the solutions.
