38.(ax+by)^(2)+(bx-ay)^(2)

2 (ax+by)^(2)-(bx+ay)^(2)

(ax+by)^(2)-(ay+bx)^(2)

Factorise : (v) (ax + by )^(2) + (bx - ay)^(2)

Fractorise: (ax + by) ^(2) + (bx - ay)^(2)

The area of the triangle formed by pair of line (ax+by)^2-3(bx-ay)^2=0 " and the line " ax+by+c=0 is

The bisectors of the angles between the lines (ax+by)^2=c(bx-ay)^2,c gt0 are respectively parallel and perpendicular to the line bx-ay+mu=0

The slope of angular bisector of line (ax+by)^2=c(bx-ay)^2,(cgto) are

Factorise: ax ^(2) + by^(2) + bx^(2) + ay^(2)

Factorize: ax+bx+ay+byax^(2)+by^(2)+bx^(2)+ay^(2),a^(2)+bc+ab+acax-ay+bx-by

If bx=ay then show that (x^(2)+y^(2))(a^(2)+b^(2))=(ax+by)^(2)
