Simplifying 5a2 + 42a + 48 = 0 Reorder the terms: 48 + 42a + 5a2 = 0 Solving 48 + 42a + 5a2 = 0 Solving for variable 'a'. Begin completing the square. Divide all terms by 5 the coefficient of the squared term: Divide each side by '5'. 9.6 + 8.4a + a2 = 0 Move the constant term to the right: Add '-9.6' to each side of the equation. 9.6 + 8.4a + -9.6 + a2 = 0 + -9.6 Reorder the terms: 9.6 + -9.6 + 8.4a + a2 = 0 + -9.6 Combine like terms: 9.6 + -9.6 = 0.0 0.0 + 8.4a + a2 = 0 + -9.6 8.4a + a2 = 0 + -9.6 Combine like terms: 0 + -9.6 = -9.6 8.4a + a2 = -9.6 The a term is 8.4a. Take half its coefficient (4.2). Square it (17.64) and add it to both sides. Add '17.64' to each side of the equation. 8.4a + 17.64 + a2 = -9.6 + 17.64 Reorder the terms: 17.64 + 8.4a + a2 = -9.6 + 17.64 Combine like terms: -9.6 + 17.64 = 8.04 17.64 + 8.4a + a2 = 8.04 Factor a perfect square on the left side: (a + 4.2)(a + 4.2) = 8.04 Calculate the square root of the right side: 2.835489376 Break this problem into two subproblems by setting (a + 4.2) equal to 2.835489376 and -2.835489376.Subproblem 1
a + 4.2 = 2.835489376 Simplifying a + 4.2 = 2.835489376 Reorder the terms: 4.2 + a = 2.835489376 Solving 4.2 + a = 2.835489376 Solving for variable 'a'. Move all terms containing a to the left, all other terms to the right. Add '-4.2' to each side of the equation. 4.2 + -4.2 + a = 2.835489376 + -4.2 Combine like terms: 4.2 + -4.2 = 0.0 0.0 + a = 2.835489376 + -4.2 a = 2.835489376 + -4.2 Combine like terms: 2.835489376 + -4.2 = -1.364510624 a = -1.364510624 Simplifying a = -1.364510624Subproblem 2
a + 4.2 = -2.835489376 Simplifying a + 4.2 = -2.835489376 Reorder the terms: 4.2 + a = -2.835489376 Solving 4.2 + a = -2.835489376 Solving for variable 'a'. Move all terms containing a to the left, all other terms to the right. Add '-4.2' to each side of the equation. 4.2 + -4.2 + a = -2.835489376 + -4.2 Combine like terms: 4.2 + -4.2 = 0.0 0.0 + a = -2.835489376 + -4.2 a = -2.835489376 + -4.2 Combine like terms: -2.835489376 + -4.2 = -7.035489376 a = -7.035489376 Simplifying a = -7.035489376Solution
The solution to the problem is based on the solutions from the subproblems. a = {-1.364510624, -7.035489376}
