Answer:

→ $2{x}^{2} (x + 2) - 3x( {x}^{2} - 3) - 5x(x + 5)$

→ $2 {x}^{3} + 4 {x}^{2} - 3 {x}^{3} + 9x - 5 {x}^{2} + 25x$

→ $- 1 {x}^{3} - 1 {x}^{2} + 34x$

→ Multiply throughout by (-)

→ ${x}^{3} + {x}^{2} - 34x$

ktsingh43: i didn't understand the last step

ktsingh43: pls explain it alao

ktsingh43: also*

Sirat664: i did one mistake i just noticed , in place of +34x there will be -9x

Sirat664: in last step , we multiplied by negative sign (-) to simply expression... last step is optional

ktsingh43: no its helpful thanks

Sirat664: thank you

Answer:

-x³-x²-16x

Step-by-step explanation:

2x²(x+2)-3x(x²-3)-5x(x+5)=0

2x³+4x²-3x³+9x-5x²-25x=0

2x³-3x³+4x²-5x²+9x-25x=0

-x³-x²-16x=0

-x³-x²=0+16x

-x³=0+16x+x²

0+16x+x²+x³

x³+x²+16x+0
