Answer: 1) Let's simplify step-by-step.
x22(x+y)−y2
Distribute:
=(x22)(x)+(x22)(y)+−y2
=x23+x22y+−y2
Answer:
=x23+x22y−y2
2)Let's simplify step-by-step.
x4+x2y2+y4
There are no like terms.
Answer:
=x4+x2y2+y4
Assuming O=o
group then add like terms
1o+2a+1b-2o-1b+1o=
1o+1o-2o+2a+1b-1b=
0+2a+0=
2a
Its 58.9875 so about $59

Answer:
(x+3)(x−2)/(x+7)^2 ≥0 when x ≤ -3 or x ≥ 2.
Step-by-step explanation:
(x+3)(x−2)/(x+7)^2 ≥0
The critical values are (x + 3)(x - 2) = 0.
That is when x = -3 and x = 2.
Set up a table:
x < - 3 x = -3 -3 < x < 2 x = 2 x > 2
x + 3 -ve 0 +ve 0 +ve
x - 2 -Ve -ve -ve 0 +ve
(x+7)^2 +ve +ve +ve +ve +ve
Whole
function + ve 0 - ve 0 +ve
So the function is ≥ 0 when x ≤ -3 and x ≥ 2.
