Factorising Trinomials
When the coefficient of the highest power is 1. i.e., ax 2 bx c, when a = 1 and b and c are integers. When two binomials are multiplied the product is a trinomial. Thus (x + 4) (x + 5) = x 2 + 9x + 20 (1) (x - 4) (x - 5) = x 2 - 9x + 20 (2) In this chapter we try to express ..

x 2 - 2x - 48 = x 2 - 8x + 6x - 48 = x(x - 8) + 6(x - 8) = (x - 8) (x + 6) When the coefficient of the highest power is not unity. i.e., type ax 2 bx c, when and b and c are integers. Multiply (3x + 2) (x + 4) and consider the result so obtained. = 3x (x + 4) +2 (x + 4) = 3..

. The linear asymptote which is neither horizontal nor vertical is called slant or oblique asymptote . When the numerator is of exactly one degree more than the denominator slant asymptote occurs. Using long division method, divide the numerator by the denominator and equate the quotient so obtaine..

Really helpful and explained things very clearly! Even though my session got over I can complete my homework myself
The tutor made sure i was learning and made sure i was paying attention, superbbbb session. Thank u
The tutor took time to look at the examples in my text book which show how the end product should be posted.. that always helps ,It's a great service
I have browsed many mathematics sites. But this one is the best. It focuses on the important points and leaves out the unimportant ones. The summaries are great for memorising things in a fast way.
