i don't get how the teacher got ====> x^2-14x+24

from =======> 4x+1=x^2-10+25

the question is

5- square root 4x+1 = x

so i first square everything and move the 5 over

making it -5

i then square the x, and i got 25 (bc 25 square is 5) and i double up the middle making it -10

so this is what i got also

4x+1=x^2-10+25

but i don't know how he went from =====> 4x+1=x^2-10+25

to=====> x^2-14x+24

please help

Thanks
