Question

evaluate the expression when a=14 and b=6 a+b2a-2bsimplify

Answer 1

For the expression

$a+b^2$

a=14 and b=6

Replace the expression with the given values for the variables

$\begin{gathered} 14+6^2 \\ 14+36 \\ 50 \end{gathered}$

Note: remember the order of operations, solve the exponent first and then the addition.

For the expression

$a-2b$

Just as before, replace with a=14 and b=6

$\begin{gathered} 14-2\cdot6 \\ 14-12 \\ 2 \end{gathered}$

Note: remember the order of operations, the multiplication goes first and then the subtraction.
