Question

Match the following columns.

• A. $y^2+x^2$
• B. $0$
• C. $x^2$
• D. $\frac{5z}{4}$

Answer 1

$5x^2\&4x^2$ are like terms so, these terms can be subtracted.
$5x^2-4x^2=x^2$
$x^2\&y^2$ are unlike terms so, these terms can not be combined.
$z\&\frac{z}{4}$ are like terms so, these terms can be combined.
$\frac{x^2}{x}=x\&x$ are like terms so, these terms can be subtracted.
