Simplifying t2 + -3tx + -28x2 = 0 Reorder the terms: -3tx + t2 + -28x2 = 0 Solving -3tx + t2 + -28x2 = 0 Solving for variable 't'. Factor a trinomial. (t + -7x)(t + 4x) = 0Subproblem 1
Set the factor '(t + -7x)' equal to zero and attempt to solve: Simplifying t + -7x = 0 Solving t + -7x = 0 Move all terms containing t to the left, all other terms to the right. Add '7x' to each side of the equation. t + -7x + 7x = 0 + 7x Combine like terms: -7x + 7x = 0 t + 0 = 0 + 7x t = 0 + 7x Remove the zero: t = 7x Simplifying t = 7xSubproblem 2
Set the factor '(t + 4x)' equal to zero and attempt to solve: Simplifying t + 4x = 0 Solving t + 4x = 0 Move all terms containing t to the left, all other terms to the right. Add '-4x' to each side of the equation. t + 4x + -4x = 0 + -4x Combine like terms: 4x + -4x = 0 t + 0 = 0 + -4x t = 0 + -4x Remove the zero: t = -4x Simplifying t = -4xSolution
t = {7x, -4x}
