4x+12y=1; 6x+9y=1
3x+5y=1; 2x+3y=5
x^2+6xy+9y^2=36; x-2y=1
Canonical form:
x^2+6xy+9y^2
Identical expressions
x^ two +6xy+9y^ two = thirty-six ; x-2y= one
x squared plus 6xy plus 9y squared equally 36; x minus 2y equally 1
x to the power of two plus 6xy plus 9y to the power of two equally thirty minus six ; x minus 2y equally one
x2+6xy+9y2=36; x-2y=1
x²+6xy+9y²=36; x-2y=1
x to the power of 2+6xy+9y to the power of 2=36; x-2y=1
Similar expressions

x  + 6*x*y + 9*y  = 36

$$9 y^{2} + \left(x^{2} + 6 x y\right) = 36$$

x - 2*y = 1

$$x - 2 y = 1$$

x - 2*y = 1
