Q. Solve using the quadratic formula.4u2+8u+4=0Write your answers as integers, proper or improper fractions in simplest form, or decimals rounded to the nearest hundredth.u=_____ or u=_____
Identify values of a, b, c: Identify the values of a, b, and c in the quadratic equation4u2+8u+4=0. The quadratic equation is in the form au2+bu+c=0. Here, a=4, b=8, and b0.
Substitute values into formula: Substitute the values of a, b, and c into the quadratic formula u=2a−b±b2−4ac.u=2⋅4−(8)±(8)2−4⋅4⋅4
Simplify discriminant: Simplify the expression under the square root (the discriminant). (8)2−4⋅4⋅4=64−64=0
Find real solution: Since the discriminant is 0, there is only one real solution to the equation.u=8−8±0
Simplify to find u: Simplify the equation to find the value of u.u=(8−8±0)u=8−8u=−1
