Step-by-step explanation:

(5x+6) × (9x-4)

5x(9x-4) + 6(9x-4)

45x² - 20x + 54x - 24

= 45x² + 34x - 24

Answer 2

$\LARGE{\bf{\underline{\underline{Question:-}}}}$

Multiply:-

(5x + 6) and (9x - 4)

$\LARGE{\bf{\underline{\underline{Solution:-}}}}$

(5x + 6) × (9x - 4)

= (5x + 6)(9x - 4)

= 5x(9x - 4) + 6(9x - 4)

= 45x² - 20x + 54x - 24

= 45x² + 34x - 24

Or,

(5x + 6) × (9x - 4)

= (5x + 6)(9x - 4)

= 9x(5x + 6) - 4(5x + 6)

= 45x² + 54x - 20x - 24

= 45x² + 34x - 24

$\LARGE{\bf{\underline{\underline{Required \ Answer:-}}}}$

On multiplying (5x + 6) and (9x - 4), we will get

45x² + 34x - 24.
