Q. Solve using the quadratic formula.6w2+7w−2=0Write your answers as integers, proper or improper fractions in simplest form, or decimals rounded to the nearest hundredth.w=_____ or w=_____
Identify coefficients: Identify the coefficients of the quadratic equation.The quadratic equation is in the form ax2+bx+c=0. For the equation 6w2+7w−2=0, the coefficients are:a = 6b = 7c = −2
Substitute into formula: Substitute the coefficients into the quadratic formula.The quadratic formula is w=2a−b±b2−4ac. Substituting the values we get:w=2(6)−(7)±(7)2−4(6)(−2)
Simplify discriminant: Simplify the expression under the square root (the discriminant).Calculate the discriminant: (7)2−4(6)(−2)=49+48=97
Continue with formula: Continue with the quadratic formula using the discriminant.w=2(6)−7±97w=12−7±97
Calculate solutions: Calculate the two possible solutions for w.First solution: w=12−7+97Second solution: w=12−7−97
Simplify and round: Simplify the solutions and, if necessary, round to the nearest hundredth.First solution: w≈(12−7+9.85)≈122.85≈0.24Second solution: w≈(12−7−9.85)≈12−16.85≈−1.40
