X^2 - 8x = 3 by completing the square

Anit [1.1K]

<h2>Solving Quadratic Equations by Completing the Square Method</h2><h3>Answer:</h3>

$x = 4 +\sqrt{19}$ and $x = 4 -\sqrt{19}$

<h3>Step-by-step explanation:</h3>

Recall:

$x^2 -2ax +a^2 = (x -a)^2$

$x^2 -8x = 3 \\ x^2 -8x +16 = 3 +16 \\ (x -4)^2 = 19 \\ x -4 = ±\sqrt{19} \\ x = 4 ±\sqrt{19}$

The volume formula for a pyramid is:

$V=\frac{1}{3}Bh$

The B stands for the area of the base, which in this case is a right triangle. We will find the area of the right triangle first, then plug it into the equation.

The area formula for a triangle is:

$A=\frac{1}{2}bh$

Plug in the numbers.

$A=\frac{1}{2}*9*10$

A = 45

Now we have found the area of B, we can plug it into the volume formula for the pyramid.

$V=\frac{1}{3}*45*8$

V = 120 in^3
