Solution
What To Do Let x be the number Use a variable to represent the unknown + 15 Translate into mathematical expression Place polynomial on one side and set equation to zero by Additive Inverse Property x² + 15 - = 8x - 2 + 15 - 8x = Write the resulting equation x2 8x + = Arrange the terms in descending order of its exponents ()() = 0 Factor the polynomial (X - _) = 0 or (x – -) = 0 Apply the Zero Property x- 5 + - = 0+ - OT Solve for the unknown by using Additive Inverse Property x + 3 = 0 + Write the resulting equation. 01
