How to fill out 9-5 solving quadratic equations
How to fill out 9-5 solving quadratic equations:
01
Start by examining the quadratic equation in the form of ax^2 + bx + c = 0, where a, b, and c are coefficients.
02
Identify the values of a, b, and c from the given equation.
03
Use the quadratic formula, x = (-b ± √(b^2 - 4ac))/(2a), to solve for the values of x.
04
Substitute the corresponding values of a, b, and c into the quadratic formula.
05
Simplify the equation under the square root and calculate the discriminant, D = b^2 - 4ac.
Depending on the discriminant value, there are three scenarios to consider:
01
If D > 0, the quadratic equation has two distinct real roots.
02
If D = 0, the quadratic equation has one real root, known as a "double root" or "repeated root."
03
If D < 0, the quadratic equation has two complex conjugate roots.
3.1
Apply the quadratic formula to derive the values of x based on the appropriate scenario.
3.2
Simplify the obtained radicals or fractions, if necessary, to express the roots in their simplest form.
3.3
Check your solutions by substituting the calculated values of x back into the original equation and verifying that it satisfies the equation.
