Q.

x(1400 x+6)+2(2x+4)

\newline

The expression shown above can be expressed as

cx^{2}+kx+m

, where

c

,

k

, and

m

are constants. What is the value of

k

?

\newline

_____

Distribute $2$ across expression: Now we have $1400x^2 + 6x$ . $\newline$ Next, distribute the $2$ across $(2x + 4)$ . $\newline$ Calculation: $2 \times 2x + 2 \times 4$
Combine distributed terms: That gives us $4x + 8$ . Now, let's add the two parts together: $1400x^2 + 6x + 4x + 8$ . Calculation: $1400x^2 + (6x + 4x) + 8$
Combine like terms: Combine like terms to find the coefficient of $x$ . $\newline$ Calculation: $6x + 4x = 10x$
Final expression: So the expression becomes $1400x^2 + 10x + 8$ . The coefficient of $x$ , which is $k$ , is $10$ .
