X² - 8x - 33=0<br> complete the square
Andreas93 [3]
<h2>Answer:</h2><h2></h2><h2>\boxed{x_{1}=-3} \\ \\ \boxed{x_{2}=11}</h2>

<h2>Explanation:</h2>

Step 1. Write x^2 - 8x - 33=0 in the form x^2+2ax+a^2=0

2a=-8\quad :\quad a=-4

Step 2. Add and subtract (-4)^2 to the left side of the equation

x^2-8x-33+\left(-4\right)^2-\left(-4\right)^2=0 \\ \\ \\ But: \\ \\  x^2+2ax+a^2=\left(x+a\right)^2 \\ \\ x^2-8x+\left(-4\right)^2=\left(x-4\right)^2

Step 3. Complete square

\left(x-4\right)^2-33-\left(-4\right)^2=0 \\ \\ \left(x-4\right)^2-49=0 \\ \\ (x-4)=\pm \sqrt{49} \\ \\ x-4=\pm 7 \\ \\ \boxed{x_{1}=-3} \\ \\ \boxed{x_{2}=11}
