Final answer:
The quadratic formula can be used to solve quadratic equations by substituting the given values of a, b, and c into the formula and simplifying the expression.
Step-by-step explanation:
The solution to a quadratic equation can be found by applying the quadratic formula. The quadratic formula is given by:
x = (-b ± √(b²-4ac))/(2a)
where a, b, and c are the coefficients of the quadratic equation ax²+bx+c=0. To solve for x, substitute the values of a, b, and c into the quadratic formula and simplify the expression. Then use the + and - signs to find the two possible values of x.
