Question

What is the coefficient of -x in $-42x{y}^3{z}^2$?

• A. -42$y^3$z^2$
• B. 42$y^3$z^2$
• C. -42
• D. 42

Answer 1

The correct option is B 42$y^3$z^2$

Any factor of an algebraic quantity is called the coefficient of the remaining quantity, along with its sign.
So in the case of the given algebraic expression, $-42x{y}^3{z}^2$, the coefficient of -x will be the remaining factors of '-x' in that expression.
Hence, the coefficient of -x is $42y^3{z}^2$
