`x^2-(a+b)x+ab`

If sin A and sin B of a triangle ABC satisfy c^(2)x^(2)-c(a+b)x+ab=0, then the triangle is

In a Delta ABC, ifsin Aandsin B are the roots of the equation c^(2)x^(2)-c(a+b)x+ab=0 then find /_C .

Factorise. x^2-x(a+2b)+2ab

Expand 4(a^2 +b^2 + x^2) -10(a+b)x + 17ab

Solve 9x^(2)-9(a+b)x+5ab+2b^(2)=0 .

If the sines of the angle A and B of a triangle ABC satisfy the equation c^(2) x^(2) - c (a + b) x + ab = 0 , then the triangle

If the equation x^(2)+(a+b)xy+aby^(2)+x+ab=0 represents two parallel lines, then

Solve for x : 9x^2-9(a+b)x+(2a^2+5ab+2b^2)=0

If the roots of the equation c^(2)x^(2)- c(a+b)x + ab =0 are sin A, sin B where A, B and C are the angles and a, b, c are the opposite sides of a triangle, then the triangle is : (i) right angled (ii) acute angled (iii) obtuse angled (iv) sin A + cos A = (a+b)/(c )
