Ineed with 2b.
the topic is rational equations and restrictions are 2 and 0.

as my answer i got 0 = 8 but i’m unsure if that’s

The answer to your question

a) Values excluded = -2, 0

b) solutions = -2/3, 2

Step-by-step explanation:

Equation

a) x is restricted when the denominators equal zero, so let's get them.

                 2x + 4 = 0                           2x =  0

                 2x = - 4                                  x = 0 / 2

                 x = -4 / 2                               x = 0

                 x = -2

x must be different to -2, 0

b)                  

                      4x² = (x + 2)²

                      4x² = x² + 4x + 4

                     4x² - x² - 4x - 4 = 0

                      3x² - 4x - 4 = 0

                      3x² - 6x + 2x - 4 = 0

                     3x(x - 2) + 2(x - 2) = 0

                     (x - 2)(3x + 2) = 0

                      x₁ - 2 = 0                  3x₂ + 2 = 0

                     x₁ = 2                         x₂ = -2/3
