Question

Simplify 3x²+5xy-4y²+x²-8xy-5y²

Answer 1

Answer:

We have,

${3x}^{2} + 5xy - {4y}^{2} - {x}^{2} - 8xy - {5y}^{2}$

$= {3x}^{2} + {x}^{2} - {4y}^{2} - {5y}^{2} + 5xy - 8xy$

$= {3</p><p>4x}^{2} - {9y}^{2} - 3xy$

Answer 2

Step-by-step explanation:

3x2+×2+5xy -8xy -4y2-5y2

=4x2-3xy-9y2
