Simplifying 3t2 + -4t + -7 = 20 Reorder the terms: -7 + -4t + 3t2 = 20 Solving -7 + -4t + 3t2 = 20 Solving for variable 't'. Reorder the terms: -7 + -20 + -4t + 3t2 = 20 + -20 Combine like terms: -7 + -20 = -27 -27 + -4t + 3t2 = 20 + -20 Combine like terms: 20 + -20 = 0 -27 + -4t + 3t2 = 0 Begin completing the square. Divide all terms by 3 the coefficient of the squared term: Divide each side by '3'. -9 + -1.333333333t + t2 = 0 Move the constant term to the right: Add '9' to each side of the equation. -9 + -1.333333333t + 9 + t2 = 0 + 9 Reorder the terms: -9 + 9 + -1.333333333t + t2 = 0 + 9 Combine like terms: -9 + 9 = 0 0 + -1.333333333t + t2 = 0 + 9 -1.333333333t + t2 = 0 + 9 Combine like terms: 0 + 9 = 9 -1.333333333t + t2 = 9 The t term is -1.333333333t. Take half its coefficient (-0.6666666665). Square it (0.4444444442) and add it to both sides. Add '0.4444444442' to each side of the equation. -1.333333333t + 0.4444444442 + t2 = 9 + 0.4444444442 Reorder the terms: 0.4444444442 + -1.333333333t + t2 = 9 + 0.4444444442 Combine like terms: 9 + 0.4444444442 = 9.4444444442 0.4444444442 + -1.333333333t + t2 = 9.4444444442 Factor a perfect square on the left side: (t + -0.6666666665)(t + -0.6666666665) = 9.4444444442 Calculate the square root of the right side: 3.073181486 Break this problem into two subproblems by setting (t + -0.6666666665) equal to 3.073181486 and -3.073181486.Subproblem 1
t + -0.6666666665 = 3.073181486 Simplifying t + -0.6666666665 = 3.073181486 Reorder the terms: -0.6666666665 + t = 3.073181486 Solving -0.6666666665 + t = 3.073181486 Solving for variable 't'. Move all terms containing t to the left, all other terms to the right.
