If `a = 2` & `b = 5`, then `(x+a)(x + b)` is equal to :

If lim_(x to 1) (x^(2) - ax + b)/(x-1)=5," then " a + b is equal to

If (x + 2) is a common factor of x^(2) + ax + b and x^(2) + bx + a , then the ratio a : b is equal to

The function f(x)=e^(x^(3)-6x^(2)+10) attains local extremum at x = a and x = b (a < b), then the value of a+b is equal to

If A = (2x + 1)/(2x - 1) and B = (2x - 1)/(2x + 1) then A - B is equal to:

If (2a+2b-x)=f(x), then int_(2a)^(2b)xf(x)dx is equal to

Let X~B(n,p) , if E(X)=5,Var(X) =2.5 then P(X lt 1) is equal to

If A={x:x is a multiple of 2},B={x:x is a multiple of 5} and C={x,x is a multiple of 10}, then A nn(B nn C) is equal to
