Question

How do I find the x intercept for f(x)=x^2+x-2/x^2-3x-4

Answer 1

x-intercept means where it crosses the x-axis
which means where y (or in this case, f(x) ) = 0

solve for the x values where
x^2+x-2/x^2-3x-4=0

Answer 2

for that to be zero, the top part must be zero, so solve for
x^2 +x-2=0

Answer 3

So x=-2 and x=1 for the top

Answer 4

Would I put both numbers or just choose one? @phi

Answer 5

both

Answer 6

Okay thank you so much!
