(x² - 17x-60) + (x²+2x+1) = 2
Answer (1)
1. Combine like terms on the left: (x² - 17x - 60) + (x² + 2x + 1) = 2→ 2x² - 15x - 59 = 22. Move 2 to the left: 2x² - 15x - 59 - 2 = 0→ 2x² - 15x - 61 = 03. Use quadratic formula, x = [15 ± √(713)] / 4Exact roots: x = (15 + √713) / 4 and x = (15 - √713) / 4Approximate values: x ≈ 10.426 and x ≈ -2.926
