Answer 2

Solving the Quadratic Equation

To solve the quadratic equation 49x + 14x^2 = 0, we can use the quadratic formula: x = (-b ± √(b^2 - 4ac)) / (2a), where a, b, and c are the coefficients of the quadratic equation ax^2 + bx + c = 0.

Applying the Quadratic Formula

In this case, the coefficients are: - a = 14 - b = 49 - c = 0

Using the quadratic formula, we can calculate the roots of the equation.

Calculation

The quadratic formula gives us: x = (-49 ± √(49^2 - 4*14*0)) / (2*14)

Solving the discriminant: √(49^2 - 4*14*0) = √(2401) = 49

So, the roots of the equation are: x = (-49 + 49) / 28 = 0 / 28 = 0 x = (-49 - 49) / 28 = -98 / 28 = -3.5

Therefore, the solutions to the equation 49x + 14x^2 = 0 are x = 0 and x = -3.5.
