Q. Solve using the quadratic formula.3j2+3j−8=0Write your answers as integers, proper or improper fractions in simplest form, or decimals rounded to the nearest hundredth.j=_____ or j=_____
Identify coefficients: Identify the coefficients a, b, and c in the quadratic equation3j2+3j−8=0.a=3, b=3, c=−8
Write quadratic formula: Write down the quadratic formula: j=2a−b±b2−4ac.
Substitute values: Substitute the values of a, b, and c into the quadratic formula.j=2(3)−(3)±(3)2−4(3)(−8)
Simplify expression: Simplify the expression under the square root (the discriminant). (3)2−4(3)(−8)=9+96=105
Simplify formula: Simplify the quadratic formula with the values. j=6−3±105
Calculate solutions: Calculate the two possible solutions for j.j=6−3+105 or j=6−3−105
Round values: Round the values of j to the nearest hundredth, if required.j \approx (\-3 + 10.25) / 6 or j \approx (\-3 - 10.25) / 6j≈7.25/6 or j≈−13.25/6j≈1.21 or j≈−2.21
