Answer:
(-4,27)
Step-by-step explanation:
Let combine each equations
[tex] {x}^{2} - 2 x + 3 = - 2x + 19[/tex]
[tex] {x}^{2} - 16[/tex]
We know 4 is a root already so this means that our next root have to be
[tex] \frac{ {x}^{2} - 16 }{x - 4} = x + 4[/tex]
So set the quotient equal to zero.
[tex]x + 4 = 0[/tex]
[tex]x = - 4[/tex]
Plug -4 into one of the equations.
[tex] - 2( - 4) + 19 = 27[/tex]
