Question

factorie 3x³+14x²-7x+10​

Answer 1

Answer:

3x³ - 14x² - 7x + d = (x + 1)(ax² + bx + c) -------------------------- (x + 1)(ax² + bx + c) = ax³ + bx² + cx + ax² + bx + c = ax³ + (a + b)x² + (b + c)x + c -------------------------- ax³ + (a + b)x² + (b + c)x + c = 3x³ - 14x² - 7x + d => a = 3 a + b = -14 b + c = -7 c = d => a = 3, b = -17, c = 10, d = 10
