Question

$\huge{\underline{\mathtt{\red{q}\pink{u}\green{e}\blue{s}\purple{t}\orange{i}\blue{o}\purple{n}}}}$

Subtract:
3x²– 5x + 7 from 5x² – 7x + 9​

Answer 1

$\huge{\underline{\mathtt{\red{A}\pink{N}\green{S}\blue{W}\purple{E}\orange{R}}}}$

(5x2 – 7x + 9) – (3x2 – 5x + 7)

= 5x2 – 7x + 9 – 3x2 + 5x – 7

= 5x2 – 3x2 + 5x – 7x + 9 – 7

= 2x2 – 2x + 2 AnSwEr..

Answer 2

$\huge{ \mathtt{ \underline{ \blue{Solution}}}}$

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

$\sf{ = 5 {x}^{2} - 7x + 9 - 3 {x}^{2} + 5x - 7}$

$\sf{ = 2x {}^{2} - 2x + 2}$

$\sf{ \orange{ \boxed{ = 2( {x}^{2} - x + 1)}}}$

Hope this helps you✌
