Simplifying 2a2 + 20a = -64 Reorder the terms: 20a + 2a2 = -64 Solving 20a + 2a2 = -64 Solving for variable 'a'. Reorder the terms: 64 + 20a + 2a2 = -64 + 64 Combine like terms: -64 + 64 = 0 64 + 20a + 2a2 = 0 Factor out the Greatest Common Factor (GCF), '2'. 2(32 + 10a + a2) = 0 Ignore the factor 2.Subproblem 1
Set the factor '(32 + 10a + a2)' equal to zero and attempt to solve: Simplifying 32 + 10a + a2 = 0 Solving 32 + 10a + a2 = 0 Begin completing the square. Move the constant term to the right: Add '-32' to each side of the equation. 32 + 10a + -32 + a2 = 0 + -32 Reorder the terms: 32 + -32 + 10a + a2 = 0 + -32 Combine like terms: 32 + -32 = 0 0 + 10a + a2 = 0 + -32 10a + a2 = 0 + -32 Combine like terms: 0 + -32 = -32 10a + a2 = -32 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 = -32 + 25 Reorder the terms: 25 + 10a + a2 = -32 + 25 Combine like terms: -32 + 25 = -7 25 + 10a + a2 = -7 Factor a perfect square on the left side: (a + 5)(a + 5) = -7 Can't calculate square root of the right side.
