Question

The co efficient of x² in (5-2x)(7x + 5x²-x³)​

Answer 1

Answer:

The coefficient of x²is 5

Answer 2

Step-by-step explanation:

The given expression is

$(5 - 2x)(7x + 5 {x}^{2} - {x}^{3})$

Now, the terms containing x²are

25x² - 14 x²

=> (25 - 14)x²

=>11 x²

So, coeeficient of x² is 11
