1.5a(10a^(2)b-100ab^(2))

Simplify (5a-2b) (25a^(2)+10ab+4b^(2)_) -(2a+5b) (4a^(2)-10ab+25b^(2)).

Simplify that: (4ab^(2)(-5ab^(3)))/(10a^(2)b^(2))

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

Find the value of (5a^(6))x(-10ab^(2))x(-2.1a^(2)b^(3)) for a=1 and b=(1)/(2)

If a:b=2:3, then the value of (5a^(3)-2a^(2)b):(3ab^(2)-b^(3)) is :

If a=(sqrt(5)+sqrt(2))/(sqrt(5)-sqrt(2)) and b=(sqrt(5)-sqrt(2))/(sqrt(5)+sqrt(2)), find the value of (a^(2)+ab+b^(2))/(a^(2)-ab+b^(2))

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

Find the value of the expressions, when a= -1" and "b= 3 5a^(2)+4ab^(2)-8a^(2)b .
