Question

lf m=2,n=3 then find 4m²-3n²+mn​

Answer 1

Answer:

-5 is the answer

Step-by-step explanation:

4m²-3n²+mn​

put m = 2 and n =3

4(2)² - 3(3)² + 2(3)

= 4(4) - 3 (9) + 6

= 16 - 27 + 6

= 22 - 27

= -5

Answer 2

Given that,

m = 2

n = 3

$the \: value \: of \: {4m}^{2} - {3n}^{2} + mn \\ 4 \times {(2)}^{2} - 3 \times {(3)}^{2} + 2 \times 3 \\ 4 \times 4 - 3 \times 9 + 6 \\ 16 - 18 + 16 \\ 32 - 18 \\ 14$

Therefore, your answer is 15
