Answer 1

\[\frac{n^2-10n+24}{n^2-13n+42}=\frac9{n-7}\]

simplify the right hand side by factoring the numerator and the denominator

Answer 2

\[n^2−10n+24=0\]you might want to use the quadratic formula
\[ax^2+bx+c=0\]\[x_{1,2}=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\]\[(x-x_1)(x-x_2)=0\]

Answer 3

how is that ??

Answer 4

pardon?

Answer 5

yuhh
