Question

explain what is quadratic equation, give 5 examples and what are their types explain​

Answer 1

Answer:

an equation containing a single variable of degree 2. Its general form is ax2 + bx + c = 0, where x is the variable and a, b, and c are constants (a ≠0)

Examples of Quadratic Equation

6x² + 11x - 35 = 0.

2x² - 4x - 2 = 0.

-4x² - 7x +12 = 0.

20x² -15x - 10 = 0.

x² -x - 3 = 0.

5x² - 2x - 9 = 0.

3x² + 4x + 2 = 0.

-x² +6x + 18 = 0.

Here are the three forms a quadratic equation should be written in:

1) Standard form: y = ax2 + bx + c where the a,b, and c are just numbers.

2) Factored form: y = (ax + c)(bx + d) again the a,b,c, and d are just numbers.

3) Vertex form: y = a(x + b)2 + c again the a, b, and c are just numbers.

thx my all answers...

Answer 2

An equation in the form

ax²+bx+ c=0 is called a quadratic equation.
