a, you take the value of f(x) then subtract 4 giving you a
Answer:
Answer is The last one angle DFE
Answer:
(3x +2)(x +1)
Step-by-step explanation:
A number of different ways are suggested for doing this. One that seems straightforward is this.
For ax^2 +bx +c, look for factors of ac that total b. Here we have ...
ac = 3·2 = 6
b = 5
It is easy to see that the factors we just multiplied to get 6 are ones that total 5: 3+2 = 5.
Now, rewrite the "bx" term using this sum.
3x^2 +3x +2x +2
Factor each pair of terms.
3x(x +1) +2(x +1)
And factor out the common factor:
(3x +2)(x +1)
1. To find the square root, you have to square root them both.
Square root of 324 is 18, so x=-18, 1818
2. Divide 49 by 9. 49/9=5.44 then find the square root of 5.44 which is 2.3, x=-2.3, 2.3.
3. To do this one it is one of either 2 or 4 because it is not a perfect square, it can break down to square root of 16 and square root of 6, which then makes it +-4 square root 6.
4. This one is simple the square root of 34 is 5.8
5. Subtract each by 5 to get 6y^2=215 then divide each by 6. Y^2=34.8 then square root. Which makes y=+-5.9. Hope this helped.
