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)

the last one is correc5

Step-by-step explanation:

this is because x^2 times x equals x^3

then you do x^2 times 11 which is 11x^2

then -3 times x which is -3x

then -3 times 11 which is -33

step-by-step explanation:

the multiplicative inverse of a fraction a/b is b/a. for the multiplicative inverse of a real number, divide 1 by the number. for example, the reciprocal of 5 is one fifth 1/5 or 0.2, and the reciprocal of 0.25 is 1 divided by 0.25, or 4.
