Answer» ong>Answer: -x² - 30x + 32 Step-by-step EXPLANATION: Here we have (5x - 3)(x - 4) - (2x + 5)(3x - 4) First lets multiply the first term. This gives, (5x - 3)(x - 4) = 5x(x - 4) - 3(x - 4) = 5x² - 20x - 3x + 12 = 5x² - 23x + 12. Now the second term. (2x + 5)(3x - 4) 2x(3x - 4) + 5(3x - 4) 6x² - 8x + 15x - 20 = 6x² + 7X - 20. Now lets subtract them. This gives, 5x² - 23x + 12 -(6x² + 7x - 20) Thus, 5x² - 6x² - 23x - 7x + 12 + 20 = -x² - 30x + 32. |
