2x•x(62-21y)

To simplify the expression \( 2x \cdot x(62 - 21y) \), we can follow these steps:

1. Multiply the terms: \[ 2x \cdot x(62 - 21y) = 2x^2(62 - 21y) \]

2. Distribute \( 2x^2 \): \[ 2x^2 \cdot 62 - 2x^2 \cdot 21y = 124x^2 - 42x^2y \]

So, the simplified expression is: \[ 124x^2 - 42x^2y \]
