Factor the polynomial:
7p⁸ + 42p⁵ + 28p²
Factor out the greatest common divisor:
= 7p⁽² ⁺ ⁶⁾ + 42p⁽² ⁺ ³⁾ + 28p²
= 7p² · p⁶ + 7p² · 6p³ + 7p² · 4
= 7p² · (p⁶ + 6p³ + 4) <———<span>— factored form</span>
I hope this helps. =)
5 + (n - 1)²
5 + (n - 1)(n - 1)
5 + (n² - n - n + 1)
5 + (n² - 2n + 1)
n² - 2n + 1 + 5
n² - 2n + 6 = 0
n = <u>-(-2) +/- √((-2)² - 4(1)(6))</u>
2(1)
n = <u>2 +/- √(4 - 24)</u>
2
n = <u>2 +/- √(-20)
</u> 2
n = <u>2 +/- 2i√(5)</u>
2
n = 1 <u>+</u> i√(5)
n = 1 + i√(5) n = 1 - i√(5)
The answer is equal to B.
