解方程:(x^2+16x+208)^(.5)=8+(x^2-16x+208)^(.5)
2x²-16=x²+5x+8
0.5×16-16×0.2=4X 2(X-3)=5.8 (0.5+X)+X=9.8+2 25000+X=6X 7(X-2
解16(x+5)^2-8(x+5)=0
x/16=2-(4x+5)/8
8.|x+3.2x=16.5
5x-2=7x+8 3=3/2x+16 1-3/2x=3x+2/5
化简求值:x=5,求x^2-8x+16/x^2-16
4X+2(8-X)=26 2X+16=26 X=5 2X+16=26什么意思?
解方程: 2 3 X+ 2 5 X=1 5 6 X= 7 12 2X÷ 5 8 =16.
