CAN SOMEONE JUST PLEASE HELP ME ASAP PLS BRAINLIEST REWARD AND 17 POINTS

1.)

2.)

3.) Prime

Solution Steps:

______________________________

1.) :Factor the expression by grouping. First, the expression needs to be rewritten as . To find a and b, set up a system to be solved:

 -

 -

Since ab is positive, a and b have the same sign. Since is negative, a and b are both negative. The only such pair is the system solution:

 -

 -

Rewrite :

 -

Factor out x in the first and −1 in the second group:

 -

Factor out common term by using distributive property:

 -

2.) :Factor the expression by grouping. First, the expression needs to be rewritten as . To find a and b, set up a system to be solved:

 -

 -

Since ab is negative, a and b have the opposite signs. Since is positive, the positive number has greater absolute value than the negative. List all such integer pairs that give product −22:

 -

 -

Calculate the sum for each pair:

 -

 -

The solution is the pair that gives sum 9:

 -

 -

Rewrite :

 -

Factor out x in the first and 11 in the second group:

 -

Factor out common term by using distributive property:

 -

3.) :

 - This cannot be factored.
