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
