Question

Simplify : 8x³y +7x²y (3x-4y) +2xy (-3x²+4y)​

Answer 1

Question :

Simplify :

✒ :8x³y+7x²y(3x-4y)+2xy(-3x²+4y)

Solution :

$\\ \implies \quad \displaystyle\bf \: 8 {x}^{3} y + 7 {x}^{2} y(3x - 4y) + 2xy( - 3 {x}^{2} + 4y)$

$\\ \implies \quad \displaystyle \bf \: 8 {x}^{3} y + 21 {x}^{3} y - 28 {x}^{2} {y}^{2} - 6 {x}^{3} y + 8x {y}^{2}$

$\\ \implies \quad \displaystyle \bf \: 29 {x}^{3} y - 6 {x}^{3} y - 28 {x}^{2} {y}^{2} + 8x {y}^{2}$

$\\ \implies \quad \displaystyle \bf \: 23 {x}^{3} y - 4 {y}^{2} (7 {x}^{2} + 2x) = 0$
