Tìm x,y biết: x + (-31/12)^2 = (49/12)^2 - x = y^2
Tìm x,y
a, x+(–31/12)^2=(49/12)^2–x=y^2
b, x*(x-y)=3/10 và y*(x-y)=–3/20
Tìm x,y biết rằng:
x + (-31/12)2 = (49/12)2 - x = y2
Tìm x, y:
\(x+\left(\frac{-31}{12}\right)^2=\left(\frac{49}{12}\right)^2-x=y^2\)
\(x+\frac{-31}{12}^2=\frac{49}{12}^2-x=y^2\)
Tìm x,y
Tìm x;y biết rằng:
\(x+\left(-\frac{31}{12}\right)^2=\left(\frac{49}{12}\right)^2-x=y^2\)
Bài 2 Tìm x,y : \(x+\left(-\frac{31}{12}\right)^2=\left(\frac{49}{12}\right)^2-x=y^2\)
Tìm x,y biết
\(x+\left(-\frac{31}{12}\right)^2=\left(\frac{49}{12}\right)^2-x=y^2\)
x+ (-31/12)^2 = (49/12)^2- x = y^2
