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

answer: i think it is (1,-2)

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.
