Question

What is the value of x2y + 2x + 3y + 4 when x = 1 and y = 2?

Answer 1

Step-by-step explanation:

$= {x}^{2} y + 2x + 3y + 4$

$\bold{given \: x = 1 \: and \: y = 2}$

$\boxed{ \mathfrak \color{red}{solution : }}$

placing all the values

$= (1 {)}^{2} \times 2 + 2 \times 1 + 3 \times 2 + 4$

$= 1 \times 2 + 2 + 6 + 4$

$= 2 + 2 + 10$

$= 4 + 10$

$= 14$
