Question

If B=3y²+12x²+8xy, C= 6x²+8y²+6xy. Then find B-C?​

Answer 1

Answer:

e

Step-by-step explanation:

Answer 2

Answer:

$B - C = 6x^2 - 5y^2 + 2xy$

Step-by-step explanation:

$B = 3y^2 + 12 x^2 + 8xy$

$C = 6x^2 + 8 y^2 + 6xy$

$B - C = x^2(12 - 6) + y^2(3 - 8) + xy(8 - 6) = 6x^2 - 5y^2 + 2xy$
