Which of the following equations is equivalent to 4[x + 2(3x - 7)] = 22x - 65

See the equation simplified below.

Step-by-step explanation:

The equation simplifies to the following equations:

4[x + 2(3x - 7)] = 22x - 65

4[x+6x-14] = 22x - 65

4x+24x - 56 = 22x - 65

28x - 56 = 22x - 65

6x - 56 = -65

6x = -9

x = -3/2

tangent

step-by-step explanation:

let's call the solutions x₁ = (5 - 2√7)/3 and x₂ = (5 + 2√7)/3

then the equation is (x-x₁)(x-x₂) = 0

if you fill that in you get a lot of numbers which you can recognize as ax²+bx+c=0.

step-by-step explanation:

you can see that a=1 (there is just an x²)

b = (-5 -2√7 + 2√7 - 5)/3 = -10/3

c = -2√7)/3 ) * (-5+2√7)/3) = -1/3

so your answer is 3x^2 – 10x – 1 = 0
