To expand the expression 4(x+1)(x-3), we will use the distributive property.
First, multiply 4 by x and by x-3 separately:
4(x) = 4x
4(x-3) = 4(x) - 4(3) = 4x - 12
Then, add the two results together:
4x( x-3) = 4x * x + 4x * -3 = 4x^2 - 12x
Therefore, the expanded form of 4(x+1)(x-3) is 4x^2 - 12x.
4(x+1)(x-3)
