Answer:
9x + 1
Step-by-step explanation:
6x-4+3x+5
6x+3x-4+5
9x-4+5
9x+1
Let us evaluate the equations one at a time.
1) 3x + 5 = -2
3x = -7
x = -7/3
This equation has unique solution.
2) 6(x - 11) = 15 - 4x
6x - 66 = 15 - 4x
10x = 81
x = 81/10
Ths equation has a unique solution
3) 12x + 9 = 8x + 1 + 4x
12x - 8x - 4x = 1 - 9
0x = -8
x = -8/0
This equation has no solution.
4) 2(x - 3) = 10x - 6 - 8x
2x - 6 = 10x - 6 - 8x
2x - 10x + 8x = -6 + 6
0x = 0
x = 0/0
Ths equation has no solution.
5) 5x + 6 = 5x - 4
5x - 5x = -4 - 6
0x = -10
x = -10/0
This equation has no solution.

Answer:
f(x) = -4x²+24x -28
Step-by-step explanation:
The given zeros are a sum and a difference. You can use the special factoring of the product of a sum and difference to simplify the product of the factors of the quadratic. Each zero 'p' corresponds to a factor (x -p):
f(x) = a(x -(3 +√2))(x -(3 -√2)) = a((x -3)² -(√2)²) = a((x -3)² -2)
We can find the leading coefficient 'a' from the given point:
f(1) = -8 = a((1 -3)² -2) = 2a
a = -8/2 = -4
Then the function can be written as ...
f(x) = -4((x -3)² -2) = -4(x² -6x +9 -2)
f(x) = -4x²+24x -28
