Soloha48 [4]

The area is 270 inches, because you would do length times width, which in this situation is 28 and 15. You multiply them, and you get 270.

What is the answer? x^2 + 4x - 6 = 0

vodka [1.7K]

First we have to find $\Delta$ from the equation $b^{2} -4ac$ where a, b and c are consecutive coefficients of the equation. In this case: $a=1, b=4, c=-6$

 $\Delta =4^2-4*(-6)=16+24=40$ , 

Later we will need to use $\sqrt{\Delta}$ sofor us $\sqrt{40}$ . It can be then simplified to $2 \sqrt{10}$ .

Then we use quadratic formula $x=\frac{-b\pm \sqrt{\Delta} }{2a}$ to see what are the options for x.

$x=\frac{-4\pm 2\sqrt{10}}{2}$
$x=- 2 \pm \sqrt{10}$

The answer for your question:
 $x=- 2 + \sqrt{10}$ or $x=- 2 - \sqrt{10}$
