Q. Solve using the quadratic formula.2s2+9s+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 a, b, and c in the quadratic equation2s2+9s+9=0.a=2, b=9, c=9
Write quadratic formula: Write down the quadratic formula: s=2a−b±b2−4ac.
Substitute values: Substitute the values of a, b, and c into the quadratic formula.s=2(2)−(9)±(9)2−4(2)(9)
Simplify discriminant: Simplify the expression under the square root (the discriminant). (9)2−4(2)(9)=81−72=9
Calculate possible values: Calculate the two possible values for s.s=4−9±9s=4−9±3
Find solutions: Find the two solutions by performing the addition and subtraction.s = (−9+3)/4 or s = (−9−3)/4s = −6/4 or s = −12/4
Simplify fractions: Simplify the fractions to get the final answers. s=−23 or s=−3
