Answer:

(-4,27)

Explanation:

Let combine each equations

${x}^(2) - 2 x + 3 = - 2x + 19$

${x}^(2) - 16$

We know 4 is a root already so this means that our next root have to be

$\frac{ {x}^(2) - 16 }{x - 4} = x + 4$

So set the quotient equal to zero.

x + 4 = 0

x = - 4

Plug -4 into one of the equations.

- 2( - 4) + 19 = 27
