Graphical Method of Solution * The general form of a pair of a linear equations in two variables x and y are: a_{1} x + b_{1} y + c_{1}  = 0 and a_{2} x + b_{2} y + c_{2} =0 a_{1}, a_{2}, b_{1} , b_{2} , c_{1} , c_{2} are all real numbers and a_{1}² ... Read more

Geometrical Meaning of the Zero Polynomial * The x-coordinate of the point, where the graph of a polynomial intersects the x-axis is called the zero of the polynomial. * An nth-degree polynomial intersects the x-axis at maximum of n points and therefore, has a maximum of n zeroes. In a quadratic polynomial ax²+ bx + ... Read more

Real Numbers- Euclid’s Division Lemma * Euclid’s division lemma states that for any two positive integers ‘a’ and ‘b’ we can find two whole numbers ‘q’ and ‘r’ such that: a= bq + r, where 0< r < b. * Euclid’s division lemma can be used to find the highest common factor of any two ... Read more
