Q. Solve using the quadratic formula.5t2+8t−6=0Write your answers as integers, proper or improper fractions in simplest form, or decimals rounded to the nearest hundredth.t=_____ or t=_____
Identify Coefficients: Identify the coefficients of the quadratic equation.The quadratic equation is in the form at2+bt+c=0. For the equation 5t2+8t−6=0, the coefficients are:a = 5b = 8c = −6
Substitute into Formula: Substitute the coefficients into the quadratic formula.The quadratic formula is t=2a−b±b2−4ac. Substituting the values we get:t=2(5)−(8)±(8)2−4(5)(−6)
Simplify Equation: Simplify under the square root and the denominator.t=10−8±64+120t=10−8±184
Calculate Solutions: Simplify the square root (if possible) and calculate the solutions.Since 184 is not a perfect square, we will leave it under the square root. We have two possible solutions:t=10−8+184 or t=10−8−184
Round to Nearest Hundredth: Simplify the solutions further if possible and round to the nearest hundredth if necessary.t=10−8+184≈10−8+13.56 or t=10−8−184≈10−8−13.56t≈105.56 or t≈10−21.56t≈0.56 or t≈−2.16
