The resulting expression after expansion is 110x - 1200
Given the function P(x) = 140x - (30x + 1200)
To solve the literal equation, we will have to simply expand the bracket using the distributive law.
According to the law a(b+c) = ab+ac
You can see that a was distributed over "b" and "c"
For the expression, we will distribute -1 over 30x and 1300 to have;
P(x) = 140x -(30x) - (+1200)
P(x) = 140x - 30x - 1200
P(x) = 110x - 1200
Hence the resulting expression after the expansion is 110x - 1200
