Simplify the expression.
12x(x+2) - 5(2x-1)
To simplify, we need to distribute the coefficients:
12x(x+2) - 5(2x-1)
= 12x^2 + 24x - 10x + 5
= 12x^2 + 14x + 5
Therefore, the simplified expression is 12x^2 + 14x + 5.
To simplify the expression 12x(x+2) - 5(2x-1), we can start by using the distributive property to remove the parentheses:
12x(x+2) - 5(2x-1) = 12x * x + 12x * 2 - 5 * 2x - 5 * -1
Simplifying further, we get:
12x^2 + 24x - 10x + 5
Combining like terms, we have:
12x^2 + 14x + 5
So, the simplified expression is 12x^2 + 14x + 5.
