?
The quadratic equation in its standard form is ax2 + bx + c = 0, where a and b are the coefficients, x is the variable, and c is the constant term.
1 of 6
We bring the equation to the form ax²+bx+c=0, where a, b, and c are coefficients. Then use the formula:
(-b±√(b²-4ac)÷(2a)
2 of 6
Geometric Sequence
Type of sequence where the successive terms bear a constant ratio known as a common ratio e.g 2,4,6,8... having a common ratio of 2.
3 of 6
Arithmetic Sequence
A sequence where each term is obtained by adding a fixed number to its previous term e.g 1,5,9,13... with the "common difference" being 4.
4 of 6
A sequence where the first differences are NOT same but the second differences are the same e.g 1, 2, 4, 7... with a common second difference of +1
5 of 6
Fibonacci Sequence
A sequence where every term is the sum of the last two preceding terms e.g 0, 1, 1, 2, 3, 4, 7, 11...
