Question

Which shows one way to determine the factors of x3 + 11x2 – 3x – 33 by grouping?

x2(x + 11) + 3(x – 11)
x2(x – 11) – 3(x – 11)
x2(x + 11) + 3(x + 11)
x2(x + 11) – 3(x + 11)

Answer 1

Answer:

the last one is correc5

Step-by-step explanation:

then -3 times x which is -3x

then -3 times 11 which is -33
