<h3>What is Quadratic equation ?</h3>A quadratic equation as an equation of degree 2, meaning that the highest exponent of this function is 2. The standard form of a quadratic equation is y = a + bx + c, where a, b, and c are numbers and a cannot be 0
P(A) = 0.006 - 0.02a + 120
123 = 0.006- 0.02a + 120
0=0.006 - 0.02a - 3
you can use the quadratic equation formula to solve for the man's age.
A = (-b ± () ) / (2a)
A = (0.02 ± / (2*0.006)
A = (0.02 ± ) / 0.012
A = 9 , -5.67
Age of the man will be 9 years
