DESCRIPTION

EXAMPLE 2 Solve an equation with one real solutions Solve 25x 2 – 18x = 12x – 9. 25x 2 – 18x = 12x – 9. Write original equation. Write in standard form. x = 30 + (–30) 2 – 4(25)(9) 2(25) a = 25, b = –30, c = 9 Simplify. 25x 2 – 30x + 9 = 0. x = x = 3 5 Simplify. 3 5 The solution is ANSWER
