Shouldn't the equation read " (x - 4)² = 81 ", instead of "(1 - 4)² = 81" ?

If so, then the solutions are x = -5 and x = 13 .

If it's really "(1 - 4)² = 81", then that's not even an equation, and there's no solution.

Answer:

Step-by-step explanation:

The formula of a midpoint:

$M\left(\dfrac{x_1+x_2}{2};\ \dfrac{y_1+y_2}{2}\right)$

We have A(0, 0) and C(2a, 2b). Substitute:

$x=\dfrac{0+2a}{2}=\dfrac{2a}{2}=a\\\\y=\dfrac{2b+0}{2}=\dfrac{2b}{2}=b$
