Simplifying 30x2 + -20x + -10 = 8 Reorder the terms: -10 + -20x + 30x2 = 8 Solving -10 + -20x + 30x2 = 8 Solving for variable 'x'. Reorder the terms: -10 + -8 + -20x + 30x2 = 8 + -8 Combine like terms: -10 + -8 = -18 -18 + -20x + 30x2 = 8 + -8 Combine like terms: 8 + -8 = 0 -18 + -20x + 30x2 = 0 Factor out the Greatest Common Factor (GCF), '2'. 2(-9 + -10x + 15x2) = 0 Ignore the factor 2.Subproblem 1
Set the factor '(-9 + -10x + 15x2)' equal to zero and attempt to solve: Simplifying -9 + -10x + 15x2 = 0 Solving -9 + -10x + 15x2 = 0 Begin completing the square. Divide all terms by 15 the coefficient of the squared term: Divide each side by '15'. -0.6 + -0.6666666667x + x2 = 0 Move the constant term to the right: Add '0.6' to each side of the equation. -0.6 + -0.6666666667x + 0.6 + x2 = 0 + 0.6 Reorder the terms: -0.6 + 0.6 + -0.6666666667x + x2 = 0 + 0.6 Combine like terms: -0.6 + 0.6 = 0.0 0.0 + -0.6666666667x + x2 = 0 + 0.6 -0.6666666667x + x2 = 0 + 0.6 Combine like terms: 0 + 0.6 = 0.6 -0.6666666667x + x2 = 0.6 The x term is -0.6666666667x. Take half its coefficient (-0.3333333334). Square it (0.1111111112) and add it to both sides. Add '0.1111111112' to each side of the equation. -0.6666666667x + 0.1111111112 + x2 = 0.6 + 0.1111111112 Reorder the terms: 0.1111111112 + -0.6666666667x + x2 = 0.6 + 0.1111111112 Combine like terms: 0.6 + 0.1111111112 = 0.7111111112 0.1111111112 + -0.6666666667x + x2 = 0.7111111112 Factor a perfect square on the left side: (x + -0.3333333334)(x + -0.3333333334) = 0.7111111112 Calculate the square root of the right side: 0.843274043 Break this problem into two subproblems by setting (x + -0.3333333334) equal to 0.843274043 and -0.843274043.Subproblem 1
