Simplifying 2a2 + 20a = -62 Reorder the terms: 20a + 2a2 = -62 Solving 20a + 2a2 = -62 Solving for variable 'a'. Reorder the terms: 62 + 20a + 2a2 = -62 + 62 Combine like terms: -62 + 62 = 0 62 + 20a + 2a2 = 0 Factor out the Greatest Common Factor (GCF), '2'. 2(31 + 10a + a2) = 0 Ignore the factor 2.Subproblem 1
Set the factor '(31 + 10a + a2)' equal to zero and attempt to solve: Simplifying 31 + 10a + a2 = 0 Solving 31 + 10a + a2 = 0 Begin completing the square. Move the constant term to the right: Add '-31' to each side of the equation. 31 + 10a + -31 + a2 = 0 + -31 Reorder the terms: 31 + -31 + 10a + a2 = 0 + -31 Combine like terms: 31 + -31 = 0 0 + 10a + a2 = 0 + -31 10a + a2 = 0 + -31 Combine like terms: 0 + -31 = -31 10a + a2 = -31 The a term is 10a. Take half its coefficient (5). Square it (25) and add it to both sides. Add '25' to each side of the equation. 10a + 25 + a2 = -31 + 25 Reorder the terms: 25 + 10a + a2 = -31 + 25 Combine like terms: -31 + 25 = -6 25 + 10a + a2 = -6 Factor a perfect square on the left side: (a + 5)(a + 5) = -6 Can't calculate square root of the right side.
