All you have to do is combine the like terms and the answer is 6x^4-x^3-5x^2+10x+5
Answer:
g(a+b) = 3a² + 3b² - 6ab - 2a - 2b - 1
Step-by-step explanation:
<u>Given, function:</u>
<u>For the domain x= (a+b), the g(x) is:</u>
- g(a+b) = 3*(a+b)² - 2(a+b) - 1 = 3a² + 3b² - 6ab - 2a - 2b - 1
- g(a+b) = 3a² + 3b² - 6ab - 2a - 2b - 1
Answer:
No, they're not. To find the area of a circle you need to square the radius. They did not square the radius but instead multiplied it by 2.

Answer:
Step-by-step explanation:
f(x) = 2(x − 1)² + 3
= 2 ( x² - 2x +1) +3
= 2x² - 4x +2 +3
f(x) = 2x² − 4x + 5 .....standard form.
F + s = 10
| f - s | = 18
-------
This means that:
f = 10 - s
And also that:
| f - s | = 18
(f-s)²=18²
f²- 2sf + s² = 324
But f=10-s
So...
(10-s)² - 2s(10-s) + s² = 324
(10-s)(10-s) - 20s + 2s² + s² = 324
100 - 20s + s² - 20s + 2s² + s² = 324
4s² - 40s + 100 = 324
4s² - 40s + 100 - 324 = 0
4s² - 40s - 224 = 0
1/4 * (4s² - 40s - 224) = 1/4 * 0
s² - 10s - 56 = 0
(s-14)(s+4)=0
So s can be either 14 or -4.
When s = 14, f = -4.
When s = -4, f = 14.
