Simplifying 50 = 10t + -5t2 Solving 50 = 10t + -5t2 Solving for variable 't'. Reorder the terms: 50 + -10t + 5t2 = 10t + -10t + -5t2 + 5t2 Combine like terms: 10t + -10t = 0 50 + -10t + 5t2 = 0 + -5t2 + 5t2 50 + -10t + 5t2 = -5t2 + 5t2 Combine like terms: -5t2 + 5t2 = 0 50 + -10t + 5t2 = 0 Factor out the Greatest Common Factor (GCF), '5'. 5(10 + -2t + t2) = 0 Ignore the factor 5.Subproblem 1
Set the factor '(10 + -2t + t2)' equal to zero and attempt to solve: Simplifying 10 + -2t + t2 = 0 Solving 10 + -2t + t2 = 0 Begin completing the square. Move the constant term to the right: Add '-10' to each side of the equation. 10 + -2t + -10 + t2 = 0 + -10 Reorder the terms: 10 + -10 + -2t + t2 = 0 + -10 Combine like terms: 10 + -10 = 0 0 + -2t + t2 = 0 + -10 -2t + t2 = 0 + -10 Combine like terms: 0 + -10 = -10 -2t + t2 = -10 The t term is -2t. Take half its coefficient (-1). Square it (1) and add it to both sides. Add '1' to each side of the equation. -2t + 1 + t2 = -10 + 1 Reorder the terms: 1 + -2t + t2 = -10 + 1 Combine like terms: -10 + 1 = -9 1 + -2t + t2 = -9 Factor a perfect square on the left side: (t + -1)(t + -1) = -9 Can't calculate square root of the right side.
