Answer :
Final answer:
The provided equations are in the form of a quadratic equation (ax²+bx+c = 0). The solutions can be found by applying the quadratic formula (-b ± √(b² - 4ac) / 2a) to each equation.
Explanation:
All of the equations provided are of the form ax²+bx+c = 0. This is known as a quadratic equation, and its solutions, or roots, can be found using the quadratic formula: -b ± √(b² - 4ac) / 2a.
When you apply this formula to each of the equations, you'll find the values of x that make each equation true. For example, applying the quadratic formula to equation A) 5x² + 3x - 220 = 0, you would find the roots of equation A.
The same steps can be followed for equations B, C and D to ascertain their respective roots or solutions.
