Solution for (x-3)(x+7)+4(x+2)=f(x) equation: 


Simplifying
(x + -3)(x + 7) + 4(x + 2) = f(x)

Reorder the terms:
(-3 + x)(x + 7) + 4(x + 2) = f(x)

Reorder the terms:
(-3 + x)(7 + x) + 4(x + 2) = f(x)

Multiply (-3 + x) * (7 + x)
(-3(7 + x) + x(7 + x)) + 4(x + 2) = f(x)
((7 * -3 + x * -3) + x(7 + x)) + 4(x + 2) = f(x)
((-21 + -3x) + x(7 + x)) + 4(x + 2) = f(x)
(-21 + -3x + (7 * x + x * x)) + 4(x + 2) = f(x)
(-21 + -3x + (7x + x2)) + 4(x + 2) = f(x)

Combine like terms: -3x + 7x = 4x
(-21 + 4x + x2) + 4(x + 2) = f(x)

Reorder the terms:
-21 + 4x + x2 + 4(2 + x) = f(x)
-21 + 4x + x2 + (2 * 4 + x * 4) = f(x)
-21 + 4x + x2 + (8 + 4x) = f(x)

Reorder the terms:
-21 + 8 + 4x + 4x + x2 = f(x)

Combine like terms: -21 + 8 = -13
-13 + 4x + 4x + x2 = f(x)
