Question 7027: Help is this correct??
logbase3(3x-2)=2 I got x=11/3 is that right?
And... for this one solve the equation? logbase5(xsqrd+x+4)= 2 i got to xsqrd +x+4=5sqrd but i cant factor the xsqrd + x + 4 what do I do???
Thank you so much! I really appreciate it!

You can put this solution on YOUR website!
11/3 is correct

log%5B5%5D%28x%5E2%2Bx%2B4%29+=+2
x%5E2%2Bx%2B4+=+5%5E2
x%5E2%2Bx%2B4+=+25
x%5E2%2Bx-21+=+0

this does not factorise, so use the quadratic formula...answers are:

x+=+%28-1+%2B-+sqrt%2885%29%29%2F2
