Answer:

The solution set is (-3, 4).

Step-by-step explanation:

x2 + 4x - 9 = 5x + 3

x^2 + 4x - 5x - 9 - 3 = 0

x^2 -x - 12 = 0

(x - 4)(x + 3) = 0

x = -3, 4.

(3x+4)^2=14 what are the solutions?

kherson [118]

$\bf (3x+4)^2=14\implies \sqrt{(3x+4)^2}=\pm\sqrt{14}\implies 3x+4=\pm\sqrt{14}
\\\\\\
3x=\pm \sqrt{14}-4\implies x=\cfrac{\pm \sqrt{14}-4}{3}\implies x=
\begin{cases}
\cfrac{\sqrt{14}-4}{3}\\\\
\cfrac{- \sqrt{14}-4}{3}
\end{cases}$
