" 7."3+23y-8y^(2)

Resolve each of the following quadratic trinomials into factors: 7x^(2)-19x-6(2)28-31x-5x^(2)3+23y-8y^(2)(4)11x^(2)-54x+63

The locus of a point "P" ,if the join of the points (2,3) and (-1,5) subtends right angle at "P" is x^(2)+y^(2)-x-8y+13=0 x^(2)-y^(2)-x+8y+3=0 x^(2)+y^(2)-4x-4y=0,(x,y)!=(0,4)&(4,0) x^(2)+y^(2)-x-8y+13=0,(x,y)!=(2,3)&(-1,5)

Subtract 5x^(2)-4y^(2)+6y-3 from 7x^(2)-4xy+8y^(2)+5x-3y

Multiply 7x^2 by 8y^2

Find the power of the point P(2,3) with respect to the circle S = x^(2) +y^(2) -2x +8y -23 =0

Solve : (3x + 2y) (7x - 8y)

Simplify : 7x^3 +8y^3- (4x+3y)(16x^2-12xy+9y^2)

Simplify : 7x^(3)+8y^(3)-(4x+3y)(16x^(2)-12xy+9y^(2))
