YO I NEED HELP ON THIS 100 POINTS Q1: In order to complete the factoring by grouping process, what must you have before you can GROUP terms? Why is it important?

Q2: How do you approach finding the Greatest Common Factor (GCF)?

Q3: How can you check your answer after factoring?

the answer is 37

step-by-step explanation:

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.

45

step-by-step explanation:

to find a percentage, add a decimal in front and multiply it by the other number.

.25 times 180= 45
