Question

Subtract

4x ^ 2 y (5x ^ 2 - 9y - 7) from 5x y ^ 2 (8y ^ 6 - 7x + 3​

Answer 1

Question

Subtract

$\red{ \tt {5x}^{2} - 4y {}^{2} + 6y - 3 \:} \green{ \tt from \:} \blue{ \tt {7x}^{2} - 4xy + {8y}^{2} + 5x - 3y }$

$\rule{190pt}{5pt}$

Solution

$\boxed{\tt⇒ 7 {x}^{2} - 4xy + 8 {y}^{2} + 5x - 3y - 5 \times {}^2 + 4y {}^{2} - 6y + 3}$

$\red{\tt⇒ {2x}^{2} - 4xy + 12y {}^{2} + 5x - 9y + 3}$

$\rule{190pt}{2pt}$
