━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Answer:

$\boxed{ \sf{{= {4x}^{2} - 20x+11}}}$

Step-by-step explanation:

ɢɪᴠᴇɴ ǫᴜᴇsᴛɪᴏɴ :

Subtract the sum of x²- 8x + 2 and

4x² + 5x - 3 from 9x² - 7x + 10.

sᴏʟᴜᴛɪᴏɴ :

$\sf{{9x}^{2} - 7x + 10 -({4x}^{2} + 5x - 3 + {x}^{2} + 8x + 2)}$

$\sf{{9x}^{2} - 7x + 10 -{4x}^{2} - 5x + 3 - {x}^{2} - 8x - 2}$

$\sf{{9x}^{2}} - {4x}^{2} - {x}^{2} - 7x - 5x - 8x + 10 + 3 - 2$

$\implies\boxed{ \sf{{= {4x}^{2} - 20x+11}}}$
