Q. Solve the equation x2−6x−37=0 to the nearest tenth.Answer: x=
Identify Equation Type: Identify the type of equation.We have a quadratic equation in the form of ax2+bx+c=0, where a=1, b=−6, and c=−37.
Use Quadratic Formula: Use the quadratic formula to solve for x. The quadratic formula is x=2a−b±b2−4ac. Here, a=1, b=−6, and c=−37.
Calculate Discriminant: Calculate the discriminant b2−4ac.Discriminant = (−6)2−4(1)(−37)=36+148=184.
Calculate Solutions: Calculate the two solutions using the quadratic formula.x=2⋅1−(−6)±184x=26±184
Calculate First Solution: Calculate the first solution (using the + sign).x=26+184x≈26+13.5647x≈219.5647x≈9.78235Round to the nearest tenth: x≈9.8
Calculate Second Solution: Calculate the second solution (using the - sign).x=26−184x≈26−13.5647x≈2−7.5647x≈−3.78235Round to the nearest tenth: x≈−3.8
