The vertex form can also be called as standard form. The vertex form of the quadratic function is y = a(x-p)²+q, where “a” is vertical expansion/reflection and determines the direction of opening. (p , q) is the vertex, and the axis of symmetry is given by the equation x=p.
Definition Of Discriminant The Discriminant of an equation gives an idea of the number of roots and the nature of roots of the equation. If ax2 + bx + c = 0 is a quadratic equation, then the Discriminant of the equation, i.e. D = b2 – 4ac. Question: Find out the number of solutions the given equation…

Absolute Value shows how far is a number away from ‘0(zero)’. The absolute value of a real number is defined as the principle square root of the square of number. Principle Square Root: The non-negative square root of a non-negative real number, a , is called the principle square root of a and is written…
A geometric sequence is formed by multiplying each term after the 1st term by a constant, to determine the next term. The constant is the common ratio, r , of any term after the first, to the preceding term. My geometric sequence is 4, 12, 36, 108, 324,…… Part 1 : Find and . Know- =4…
