Need help help me guys,

Hello!

The denominators are equal, so we can simply combine the numerator:

Combine like terms in the numerator:

Factor out 2 from the entire fraction:

Cancel out 2 from both the numerator and denominator:

Factor the numerator to simplify further:

Cancel out x - 1:

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.
