" 5."a^(2)-b^(2)-a-b

If a=2+sqrt(3)+sqrt(5) and b=3+sqrt(3)-sqrt(5) , then a^(2)+b^(2)-4a-6b-3 is equal to

Let's resolve into factor:- 6(a + b)^2 + 5(a^2 - b^2)-6(a-b )^2

Simplify the following expression: 5a^(2)b^(2)-4a^(2)b-(-10a^(2)b^(2))

Factorise : (a+ b) ^(2) - 5( a^(2) - b^(2) ) - 24 (a-b)^(2)

Find this product : 5a^(2)b(2a - 7b)

Simplify : 6a^(2)+3ab+5b^(2)-2ab-b^(2)+2a^(2)+4ab+2b^(2)-a^(2) .

If a ne b and a^(2)=5a-3,b^(2)=5b-3 , then form that equation whose roots are a/b and b/a .

Factorise (Using factor theorem ) : 2a^(3)-5a^(2)b+6ab^(2)+3b^(3)

Express each of the products as a monomials and verify the result for x=1,y=2:((2)/(5)a^(2)b)x(-15b^(2)ac)x(-(1)/(2)c^(2))
