Simplifying 3X2 + -3X + 10 = 4 Reorder the terms: 10 + -3X + 3X2 = 4 Solving 10 + -3X + 3X2 = 4 Solving for variable 'X'. Reorder the terms: 10 + -4 + -3X + 3X2 = 4 + -4 Combine like terms: 10 + -4 = 6 6 + -3X + 3X2 = 4 + -4 Combine like terms: 4 + -4 = 0 6 + -3X + 3X2 = 0 Factor out the Greatest Common Factor (GCF), '3'. 3(2 + -1X + X2) = 0 Ignore the factor 3.Subproblem 1
Set the factor '(2 + -1X + X2)' equal to zero and attempt to solve: Simplifying 2 + -1X + X2 = 0 Solving 2 + -1X + X2 = 0 Begin completing the square. Move the constant term to the right: Add '-2' to each side of the equation. 2 + -1X + -2 + X2 = 0 + -2 Reorder the terms: 2 + -2 + -1X + X2 = 0 + -2 Combine like terms: 2 + -2 = 0 0 + -1X + X2 = 0 + -2 -1X + X2 = 0 + -2 Combine like terms: 0 + -2 = -2 -1X + X2 = -2 The X term is -1X. Take half its coefficient (-0.5). Square it (0.25) and add it to both sides. Add '0.25' to each side of the equation. -1X + 0.25 + X2 = -2 + 0.25 Reorder the terms: 0.25 + -1X + X2 = -2 + 0.25 Combine like terms: -2 + 0.25 = -1.75 0.25 + -1X + X2 = -1.75 Factor a perfect square on the left side: (X + -0.5)(X + -0.5) = -1.75 Can't calculate square root of the right side.
