Solve the equation x² + 4x − 22 = 0 Give your answers correct to 2 decimal places.
Added by Mariel T.
Step 1
The quadratic formula is given by: x = [-b ± sqrt(b² - 4ac)] / 2a In this equation, a = 1, b = 4, and c = -22. So, we can substitute these values into the quadratic formula: x = [-4 ± sqrt((4)² - 4*1*(-22))] / 2*1 Show more…
