maths(did i do this right)
posted by britney on .
write 3x*2+8x25 in the form a(x+h)*2+k where a,h and k are real numbers
formulae for h=b/2a
formulae for k=4acb^2/4a
h=8/2*3=1.33
4 (3)+ (25)8*2/4*3=152/12=12.6
3(x12.6)^2=1.33/3
x12.6=+0.67
x=0.67+3.55=4.22
x=0.67+3.55=2.88

Correct.

Idon't know!!! that's tooo hard!!
