Simplify (4 x square + 7 x -1) - (X square + 8 x - 7) + (X square + 10)

$\huge{\bold{\blue{\mathcal{ANSWER:}}}}$

4x² - x + 16

${\huge{\underline{\bf{\pink{❥Solution}}}}}$

(4xsquare + 7x - 1) - (Xsquare + 8x - 7) + (Xsquare + 10)

= (4x² + 7x -1) - (x² + 8x - 7) + (x² + 10)

= 4x² + 7x -1 - x² + 8x - 7 + x² + 10

= 4x² - x + 16
