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 values: Identify the values of a, b, and c in the quadratic equation6w2+7w+2=0. By comparing the equation to the standard form ax2+bx+c=0, we find: a=6b=7c=2
Substitute into formula: Substitute the values of a, b, and c into the quadratic formula w=2a−b±b2−4ac. Substitute a=6, b=7, and c=2 into the formula. w=2⋅6−(7)±(7)2−4⋅6⋅2
Simplify and calculate discriminant: Simplify the expression under the square root and calculate the discriminant b2−4ac.(7)2−4⋅6⋅2=49−48=1
Calculate solutions: Calculate the two possible solutions for w.Since the discriminant is 1, we have:w=2×6−7±1This gives us two solutions:w=12−7+1 and w=12−7−1
Simplify solutions: Simplify both solutions.For the first solution:w=12−7+1w=12−6w=−21For the second solution:w=12−7−1w=12−8w=−32Both fractions are already in simplest form.
Simplify solutions: Simplify both solutions.For the first solution:w=12−7+1w=12−6w=−21For the second solution:w=12−7−1w=12−8w=−32Both fractions are already in simplest form.If necessary, round the solutions to the nearest hundredth.However, since both solutions are fractions in simplest form, there is no need to round to the nearest hundredth.
