Question

~~Medal and Fan~~
I need some help, on inequalities.

X(^)2 + 7x-10 > 8

Answer 1

First Factorise it and find the critical points then test them

Answer 2

\[x ^{2}+7x-10\ge8\]
I had subtracted 8 from both sides and got
\[x ^{2}+7x-18\ge0\]

Answer 3

And what does that factorise into?

Answer 4

Thats what I need help with. See Ive never been good with factoring or even square rooting.

Answer 5

Hmm ok
