Simplifying -4t2 + -7t + -3 = 0 Reorder the terms: -3 + -7t + -4t2 = 0 Solving -3 + -7t + -4t2 = 0 Solving for variable 't'. Factor out the Greatest Common Factor (GCF), '-1'. -1(3 + 7t + 4t2) = 0 Factor a trinomial. -1((1 + t)(3 + 4t)) = 0 Ignore the factor -1.Subproblem 1
Set the factor '(1 + t)' equal to zero and attempt to solve: Simplifying 1 + t = 0 Solving 1 + t = 0 Move all terms containing t to the left, all other terms to the right. Add '-1' to each side of the equation. 1 + -1 + t = 0 + -1 Combine like terms: 1 + -1 = 0 0 + t = 0 + -1 t = 0 + -1 Combine like terms: 0 + -1 = -1 t = -1 Simplifying t = -1Subproblem 2
Set the factor '(3 + 4t)' equal to zero and attempt to solve: Simplifying 3 + 4t = 0 Solving 3 + 4t = 0 Move all terms containing t to the left, all other terms to the right. Add '-3' to each side of the equation. 3 + -3 + 4t = 0 + -3 Combine like terms: 3 + -3 = 0 0 + 4t = 0 + -3 4t = 0 + -3 Combine like terms: 0 + -3 = -3 4t = -3 Divide each side by '4'. t = -0.75 Simplifying t = -0.75Solution
t = {-1, -0.75}
