M/(4+9x)
Step-by-step explanation:
Given equation is M = 4b + 9bx.
M = 4b + 9bx
Factorizing right hand side by b:
b* (4 + 9x)
Reformulating the equation accordingly:
M = b * (4+9x)
Dividing both the left hand side and right hand side of the equation by (4+9x):
M/(4+9x) = b
=> b = M/(4+9x)
Or, In other words the required value of b is M/(4+9x)
This value of b is a function of two given variables,namely M and x, or f(M,x)

Step-by-step explanation:
Factoring a polynomial is one important way to find the roots (or x-intercepts) of the polynomial. It's not always the easiest method, particularly when the roots are mixed numbers.
If you take calculus later, you'll see that finding the derivative of a function, setting this derivative = to 0 and solving for the roots is one way in which we can identify the x-value(s) at which we have either a maximum or a minimum.
