To determine the solution of the given equation, we can use the quadratic formula which is expressed as:
x = (-b +/- √b^2 - 4ac ) / 2a
where a, b and c are the coefficients of the equation ( ax^2 + bx + c = 0)
USing the formula above we obtain the values:
x = 21
x = 3/4
Hope this answers the question. Have a nice day.
