Q. Solve using the quadratic formula.3w2−w−6=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 equation3w2−w−6=0. The standard form of a quadratic equation is ax2+bx+c=0. By comparing, we find that a=3, b=−1, and c=−6.
Substitute values: Substitute the values of a, b, and c into the quadratic formula, w=2a−b±b2−4ac. Here, a=3, b=−1, and c=−6. w=2⋅3−(−1)±(−1)2−4⋅3⋅(−6)
Calculate discriminant: Simplify the equation by calculating the discriminant (the part under the square root).Discriminant=b2−4ac=(−1)2−4⋅3⋅(−6)=1+72=73
Insert discriminant: Insert the discriminant back into the quadratic formula and simplify.w=61±73
Calculate solutions: Calculate the two possible solutions for w.w=61+73 or w=61−73
Round values: Round the values of w to the nearest hundredth, if necessary.w≈(1+8.54)/6 or w≈(1−8.54)/6w≈9.54/6 or w≈−7.54/6w≈1.59 or w≈−1.26
