The factoring can be done similarly to a quadratic equation thanks to x^4 being the square value of x^2.
<span>x^4 + 6x^2 - 7
x^4</span><span> - x^2</span> + 7x^2 - 7
(x^4 - x^2) + (<span>7x^2 - 7)
</span>x^2(x^2 - 1) + 7(<span>x^2 - 1)
</span>(x^2 + 7)(x^2 - 1)
<span>(x^2 + 7)(x - 1)(x + 1)
</span>
Factored completely we get: <span>(x^2 + 7)(x - 1)(x + 1)</span>

Area of a Square Formula: A = s²
- <em>s</em> is a side length
Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify</em>
A = 124 in²
<u>Step 2: Solve for </u><em><u>s</u></em>
- Substitute in variables [Area of a Square Formula]: 124 in² = s²
- [Equality Property] Square root both sides: s = 2√31 in
- Approximate: s = 11.1355 in
Fraction = designated group / total
So, 11/27
