1. How do you define quadratic equations?

oksian1 [2.3K]

Answer:

$ax^{2} +bx+c^{2}=0$

Step-by-step explanation:

A quadratic equation is a equation that takes the form: $ax^{2} +bx+c^{2} = 0$

Ex. Using our definition of quadratic equations, $ax^{2} +bx+c^{2}=0$ ,

We can set a = 2, b = 1, c = 6:

$2x^{2} +x+6^{2}=0$

$2x^{2} +x+36=0$

Which can then be solved (if you are trying to solve it) as:

$(2x+9)(x-8)=0$

$x=\frac{9}{2}, 8$
