Answer:
Explanation:
To simplify the expression 4x(7x+2)-8x(12x-9), we can follow these steps:
1. Distribute the 4x and the 8x to the terms inside the parentheses:
4x * 7x + 4x * 2 - 8x * 12x + 8x * (-9)
This gives us:
28x^2 + 8x - 96x^2 - 72x
2. Combine like terms:
(28x^2 - 96x^2) + (8x - 72x)
Simplifying further:
-68x^2 - 64x
So, the simplified form of the expression 4x(7x+2)-8x(12x-9) is -68x^2 - 64x.
