Step 5: Substitute the values into the quadratic formula. We have x = [-3 ± 7] / (2 * 5).
Step 6: Calculate the two possible values for x. First, for the plus sign: x = (-3 + 7) / 10 = 4 / 10 = 2/5. Second, for the minus sign: x = (-3 - 7) / 10 = -10 / 10 = -1.
Step 7: The roots of the equation are x = -1 and x = 2/5.
Quadratic Formula – The quadratic formula is used to find the roots of a quadratic equation in the form ax^2 + bx + c = 0.
Discriminant – The discriminant (b^2 - 4ac) determines the nature of the roots (real and distinct, real and equal, or complex).
Coefficient Identification – Identifying the coefficients a, b, and c from the quadratic equation is crucial for applying the formula correctly.
