Question

how do you solve this problem

(x squared - 27x) = 90 degrees (right angle)

Answer 1

\[x^2-27x=90\]
\[(x-30)(x+3)=90\] etc

Answer 2

ok well then does x=3 and x=-30 or is it just one answer?

Answer 3

\[x ^{2} - 27x =90\]

\[x ^{2} - 27x - 90 =0\]

so (x-30)(x+3) = 0

so x = 30 OR x=-3 are correct answers
