Q. Solve using the quadratic formula.3h2+8h−9=0Write your answers as integers, proper or improper fractions in simplest form, or decimals rounded to the nearest hundredth.h=_____ or h=_____
Identify coefficients: Identify the coefficients of the quadratic equation.The quadratic equation is in the form ah2+bh+c=0. For the equation 3h2+8h−9=0, the coefficients are:a=3b=8c=−9
Substitute into formula: Substitute the coefficients into the quadratic formula.The quadratic formula is h=2a−b±b2−4ac. Substituting the values of a, b, and c, we get:h=2⋅3−(8)±(8)2−4⋅3⋅(−9)
Simplify discriminant: Simplify the expression under the square root.Calculate the discriminant b2−4ac:Discriminant = (8)2−4⋅3⋅(−9)Discriminant = 64+108Discriminant = 172
Continue with formula: Continue with the quadratic formula.Now we have the discriminant, we can continue with the formula:h=6−8±172
Simplify square root: Simplify the square root, if possible.The square root of 172 cannot be simplified to an integer, so we leave it as 172.
Calculate possible solutions: Calculate the two possible solutions for h.h=6−8+172 or h=6−8−172
Round to nearest hundredth: Round the values of h to the nearest hundredth, if required.h≈(−8+13.11)/6 or h≈(−8−13.11)/6h≈5.11/6 or h≈−21.11/6h≈0.85 or h≈−3.52
