Question

x² + 4 x 4 +5 y², x² + 6 xy + 2 y²​

Answer 1

Answer:

$2x {}^{2} + 7y {}^{2} + 16 + 6xy$

first of all write the equation as it is

$x {}^{2} + 4 \times 4 + 5y {}^{2} \times x {}^{2} + 6xy + 2y {}^{2}$

take all the like terms

$x {}^{2} + x {}^{2} = 2x {}^{2}$

$5y {}^{2} + 2y {}^{2} = 7y {}^{2}$

now write it down

$2x {}^{2} + 7y {}^{2} + 16 + 6xy$
