Simplifying algebraic fractions - Factorise the numerator and denominator - Collect like terms Binomial An algebraic expression of the sum or the difference of two terms. E.g. x²-y³ Polynomial A finite expression with more than 2 terms. E.g. 6x²+24x+48 Dividend The base number that is being divided Divisor The number that is dividing into the dividend Quotient The whole number that results after dividing Remainder The number that is left over ...

MATHS A-LEVEL QUESTIONS AND ANSWERS RATED A How do you find the gradient of a line on a graph? Increase in y --------------- Increase in x How do you find the perpendicular gradient? How do you find the gradient of a line using two coordinates? y2-y1 ------ x2-x1 How do you find the equation of a straight line? y-y1 = m( x- x1) How do you find the points of intersection?
