(x+6)(x-1)
y=x2-2x+5(-1
1.log2(x)=log4(x),求x2.2^x=5^y,求x/y
Y=-x2-2x+3 -5<=x
y=(x+1)/(x2+2x+5)的值域
y=x2-2x+2(x
解方程:1/x2+x +1/x2+3x+2 +1/x2+5x+6 +1/x2+7x+12 +1/x2+9x+20=5/x2+11x-708解方程:1/x2+x +1/x2+3x+2 +1/x2+5x+6 +1/x2+7x+12 +1/x2+9x+20=5/x2+11x-708
1-1/(x2+7x+6)=(x2-5x+5)/(x 2-5x+6)
解方程5-x/x2-3x+2=5-x/x2-7x+h
集合A={y y=x2+2x-1,x∈R},B={x (2-x)(x+5)
Y=2X/(5X+1)Y=1/(X2-2X+2)
1/(x2+x)+1/(x2+3x+2)+1/(x2+5x+6)+1/(x2+7x+12)=4/21x2是x的平方
