已知x+5y=6,求:x的二次+5xy+30y已知x+5y=6,求:x的二次+5xy+30y已知x+5y=6,求:x的二次+5xy+30yx²+5xy+30y=x(x+5y)+30y=6x+

已知x+5y=6,求:x的二次+5xy+30y
已知x+5y=6,求:x的二次+5xy+30y

已知x+5y=6,求:x的二次+5xy+30y
x²+5xy+30y
=x(x+5y)+30y
=6x+30y
=6(x+5y)
=6*6
=36

x+5y=6,x的二次+5xy+30y
x的二次+5xy=x(x+5y)+30y=6x+30y=6(x+5y)
=6×6=36

x^+5xy+30y
=x(x+5y)+30y
=6x+30y
=6(x+5y)
=36

x²+5xy+30y =x(x+5y)+30y =6x+30y =6(x+5y) =6*6 =36
