If x3 − 3x2 + 3x − 7 = (x + 1) (ax2 + bx + c), then a + b + c =(a) 4(b) 12(c) −10(d) 3

If x3 − 3x2 + 3x − 7 = (x + 1) (ax2 + bx + c), then a + b + c =(a)

1.	If x3 − 3x2 + 3x − 7 = (x + 1) (ax2 + bx + c), then a + b + c =(a) 4(b) 12(c) −10(d) 3
Answer» If x³ − 3x² + 3x − 7 = (x + 1) (ax² + bx + c), then a + b + c = (a) 4 (b) 12 (c) −10 (d) 3
