Question

Solve each inequality algebraically.
x2 -4x < 5

Answer 1

subtract 5 on both sides and factor

Answer 2

-4-5 n 5-5??

Answer 3

\[x ^{2}-4x <5 \rightarrow x ^{2}-4x-5<0 \rightarrow (x-5)(x+1)<0\]

Answer 4

so the answer is x-5 n x+1

Answer 5

close, the answers are x<5 and x<-1

Answer 6

alrighty thank ya n sorry i just need alg. 2 things broken down more then what this darn online class does :/

Answer 7

completing @jigglypuff314 's answer;

taking any values of x between -1 and 5,say x=1 and plugging it into the original inequality,we have;
1^2-4(1)-5 which is <0
so we have;

since we require values of x less than 0,we then have
-1<x<5
