Simplifying -4t2 + 12t + 6 = 0 Reorder the terms: 6 + 12t + -4t2 = 0 Solving 6 + 12t + -4t2 = 0 Solving for variable 't'. Factor out the Greatest Common Factor (GCF), '2'. 2(3 + 6t + -2t2) = 0 Ignore the factor 2.Subproblem 1
Set the factor '(3 + 6t + -2t2)' equal to zero and attempt to solve: Simplifying 3 + 6t + -2t2 = 0 Solving 3 + 6t + -2t2 = 0 Begin completing the square. Divide all terms by -2 the coefficient of the squared term: Divide each side by '-2'. -1.5 + -3t + t2 = 0 Move the constant term to the right: Add '1.5' to each side of the equation. -1.5 + -3t + 1.5 + t2 = 0 + 1.5 Reorder the terms: -1.5 + 1.5 + -3t + t2 = 0 + 1.5 Combine like terms: -1.5 + 1.5 = 0.0 0.0 + -3t + t2 = 0 + 1.5 -3t + t2 = 0 + 1.5 Combine like terms: 0 + 1.5 = 1.5 -3t + t2 = 1.5 The t term is -3t. Take half its coefficient (-1.5). Square it (2.25) and add it to both sides. Add '2.25' to each side of the equation. -3t + 2.25 + t2 = 1.5 + 2.25 Reorder the terms: 2.25 + -3t + t2 = 1.5 + 2.25 Combine like terms: 1.5 + 2.25 = 3.75 2.25 + -3t + t2 = 3.75 Factor a perfect square on the left side: (t + -1.5)(t + -1.5) = 3.75 Calculate the square root of the right side: 1.936491673 Break this problem into two subproblems by setting (t + -1.5) equal to 1.936491673 and -1.936491673.Subproblem 1
t + -1.5 = 1.936491673 Simplifying t + -1.5 = 1.936491673 Reorder the terms: -1.5 + t = 1.936491673 Solving -1.5 + t = 1.936491673 Solving for variable 't'. Move all terms containing t to the left, all other terms to the right. Add '1.5' to each side of the equation. -1.5 + 1.5 + t = 1.936491673 + 1.5 Combine like terms: -1.5 + 1.5 = 0.0 0.0 + t = 1.936491673 + 1.5 t = 1.936491673 + 1.5 Combine like terms: 1.936491673 + 1.5 = 3.436491673 t = 3.436491673 Simplifying t = 3.436491673Subproblem 2
t + -1.5 = -1.936491673 Simplifying t + -1.5 = -1.936491673 Reorder the terms: -1.5 + t = -1.936491673 Solving -1.5 + t = -1.936491673 Solving for variable 't'. Move all terms containing t to the left, all other terms to the right. Add '1.5' to each side of the equation. -1.5 + 1.5 + t = -1.936491673 + 1.5 Combine like terms: -1.5 + 1.5 = 0.0 0.0 + t = -1.936491673 + 1.5 t = -1.936491673 + 1.5 Combine like terms: -1.936491673 + 1.5 = -0.436491673 t = -0.436491673 Simplifying t = -0.436491673Solution
