What else can I help you with?
How do you know if a quadratic equation will have whether or not it will have solutions?
Factorise it!
How do you check whether the equation 7x2x is quadratic?
If it doesn't have an equal sign, then it's an expression, not an equation. The expression 7x2x is quadratic, because it equals 14x², and something is quadratic if it contains the squared exponent ².
How do you solve a quadratic inequality when the expression is unfactorable?
Use the quadratic formula for the equality. Then, depending on the coefficient of x2 and the nature of the inequality [>, ≥, ≤, <], determine whether you need the open or closed intervals between the roots or beyond the roots.
What do you find when you determine the discriminant?
Whether or not that there is a solution to a quadratic equation,
What are the benefits for using the quadratic formula than factoring?
The quadratic formula is beneficial because it provides a systematic approach to finding the roots of any quadratic equation, regardless of whether they can be easily factored. It guarantees solutions even when the roots are irrational or complex, whereas factoring may not be straightforward or possible for all equations. Additionally, the quadratic formula is particularly useful for equations with coefficients that are not integers or that have larger numbers, simplifying the solving process.
