Simplifying a2 + -4a = 100 Reorder the terms: -4a + a2 = 100 Solving -4a + a2 = 100 Solving for variable 'a'. Reorder the terms: -100 + -4a + a2 = 100 + -100 Combine like terms: 100 + -100 = 0 -100 + -4a + a2 = 0 Begin completing the square. Move the constant term to the right: Add '100' to each side of the equation. -100 + -4a + 100 + a2 = 0 + 100 Reorder the terms: -100 + 100 + -4a + a2 = 0 + 100 Combine like terms: -100 + 100 = 0 0 + -4a + a2 = 0 + 100 -4a + a2 = 0 + 100 Combine like terms: 0 + 100 = 100 -4a + a2 = 100 The a term is -4a. Take half its coefficient (-2). Square it (4) and add it to both sides. Add '4' to each side of the equation. -4a + 4 + a2 = 100 + 4 Reorder the terms: 4 + -4a + a2 = 100 + 4 Combine like terms: 100 + 4 = 104 4 + -4a + a2 = 104 Factor a perfect square on the left side: (a + -2)(a + -2) = 104 Calculate the square root of the right side: 10.198039027 Break this problem into two subproblems by setting (a + -2) equal to 10.198039027 and -10.198039027.Subproblem 1
a + -2 = 10.198039027 Simplifying a + -2 = 10.198039027 Reorder the terms: -2 + a = 10.198039027 Solving -2 + a = 10.198039027 Solving for variable 'a'.
