Q. Solve using the quadratic formula.s2+6s+9=0Write your answers as integers, proper or improper fractions in simplest form, or decimals rounded to the nearest hundredth.s=_____ or s=_____
Identify coefficients: Identify the coefficients of the quadratic equations2+6s+9=0. The standard form of a quadratic equation is ax2+bx+c=0. In this case, a=1, b=6, and c=9.
Recall quadratic formula: Recall the quadratic formula: s=2a−b±b2−4ac. We will use this formula to find the values of s.
Substitute coefficients: Substitute the coefficients a, b, and c into the quadratic formula.s=2(1)−(6)±(6)2−4(1)(9)
Simplify equation: Simplify the equation by calculating the discriminant b2−4ac.s=2−6±36−36
Calculate discriminant: Since the discriminant is 0, the square root of the discriminant is also 0. s=2−6±0
Square root of discriminant: Simplify the equation further.s=2−6±0
Simplify further: Calculate the value of s.s=2−6s=−3
Calculate value of s: Since the discriminant is 0, there is only one real solution to the equation.s=−3
