This article will guide you through simplifying the expression (3x-2)(x+1)+2(x-5)^2-25 step-by-step.
Expanding the Expression
-
Expand the first product: (3x-2)(x+1) = 3x(x+1) - 2(x+1) = 3x² + 3x - 2x - 2 = 3x² + x - 2
-
Expand the second product: 2(x-5)² = 2(x-5)(x-5) = 2(x² - 5x - 5x + 25) = 2(x² - 10x + 25) = 2x² - 20x + 50
-
Combine all the terms: 3x² + x - 2 + 2x² - 20x + 50 - 25
Combining Like Terms
