How do you solve this equation? 5 + 40x = 80x² 80x² + 40x + 5 = 0 {added 80x² to both sides} 5(16x² + 8x + 1) = 0 {factored 5 out} 5(4x + 1)(4x + 1) = 0 {factored into two binomials} 4x + 1 = 0 {set the factors equal to 0, excluding the 5} 4x = 1 {subtracted 1 from both sides} x = 1/4 {divided both sides by 4} © Algebra House
