Answer:

e(x) = d(x)+4

Step-by-step explanation:

d(x) = ( x +2)^2 -4

Add 4 to each side

d(x) +4 = ( x +2)^2 -4+4

d(x) +4 = ( x +2)^2

We know that (x=2)^2 = e(x)

d(x) +4 = e(x)

e(x) = d(x)+4

Alla [95]

Answer:

x = ± 2i $\sqrt{3}$

Step-by-step explanation:

note that $\sqrt{-1}$ = i

x² = - 12 ( take square root of both sides )

x = ± $\sqrt{-12}$ = ± $\sqrt{4(3)(-1)}$ = ± 2i $\sqrt{3}$

Step-by-step explanation:

Step 1: Define Equation

3(4x - 5) - 4x + 1 = -6

Step 2: Solve for x

Distribute 3: 12x - 15 - 4x + 1 = -6
Combine like terms: 8x - 14 = -6
Isolate x term: 8x = 8
Isolate x: x = 1

Step 3: Check

Plug in x into the original equation to verify it's a solution.

Substitute in x: 3(4(1) - 5) - 4(1) + 1 = -6
Multiply: 3(4 - 5) - 4 + 1 = -6
Subtract: 3(-1) - 4 + 1 = -6
Multiply: -3 - 4 + 1 = -6
Subtract: -7 + 1 = -6
Add: -6 = -6

Here we see that -6 does indeed equal -6.

∴ x = 1 is the solution to the equation.
