Q. Solve using the quadratic formula.5u2+8u+2=0Write your answers as integers, proper or improper fractions in simplest form, or decimals rounded to the nearest hundredth.u=_____ or u=_____
Identify values: Identify the values of a, b, and c in the quadratic equation5u2+8u+2=0. Compare 5u2+8u+2=0 with the standard form ax2+bx+c=0. a=5b=8c=2
Substitute values: Substitute the values of a, b, and c into the quadratic formula to find u. The quadratic formula is u=2a−b±b2−4ac. u=2⋅5−(8)±(8)2−4⋅5⋅2
Simplify expression: Simplify the expression under the square root and the denominator. u=10−8±64−40u=10−8±24
Simplify square root: Simplify the square root of 24.24 can be simplified to 26 because 24=4×6 and 4=2.u=10−8±26
Split into solutions: Simplify the expression by splitting it into two possible solutions for u.u=10−8+26 or u=10−8−26
Simplify fractions: Simplify the fractions to find the solutions for u.u=5−4+6 or u=5−4−6
Round values: If necessary, round the values of u to the nearest hundredth.u≈(−4+2.45)/5 or u≈(−4−2.45)/5u≈−1.55/5 or u≈−6.45/5u≈−0.31 or u≈−1.29
