Answer:To find the value of x in the given quadratic equations with fractions included, we will use the quadratic formula: The quadratic formula is: Where: - a, b, and c are the coefficients of the quadratic equation ax² + bx + c = 0 1. For the first quadratic equation: x² + 7x + 6 = 0- Here, we have a = 1, b = 7, and c = 6- Substituting into the quadratic formula: - Therefore, the solutions are:- x = (-7 + 5)/2 = -1- x = (-7 - 5)/2 = -6 2. For the second quadratic equation: x² - 8x + 15 = 0- Here, we have a = 1, b = -8, and c = 15- Substituting into the quadratic formula: - Therefore, the solutions are:- x = (8 + 2)/2 = 5- x = (8 - 2)/2 = 3 Thus, the solutions for the given quadratic equations with fractions are: 1. x = -1 or x = -62. x = 5 or x = 3
