Answer:
Step-by-step explanation:
(x – 5)^2 + 3(x – 5) + 9 = 0
This is a quadratic equation in x - 5.
Let u = x - 5, then the quadratic equation becomes:
u^2 + 3u + 9 = 0
We can use the quadratic formula to solve for u.
Since u = x - 5, now we substitute x - 5 for u and solve for x.
Answer:
=x+2
Step-by-step explanation:
2(x+2)−(x+2)
Distribute the Negative Sign:
=2(x+2)+−1(x+2)
=2(x+2)+−1x+(−1)(2)
=2(x+2)+−x+−2
Distribute:
=(2)(x)+(2)(2)+−x+−2
=2x+4+−x+−2
Combine Like Terms:
=2x+4+−x+−2
=(2x+−x)+(4+−2)
=x+2
Answer:
=x+2
