Question

use sutiable identity and find the product of (x+3) (x-4)

Answer 1

Solution :

Using Identity : ( x + a ) ( x - b ) = x² - ( a + b ) x + ab

$\sf \longrightarrow$ (x + 3) ( x - 4)

$\sf \longrightarrow$ x (x - 4) + 3 ( x - 4 )

$\sf \longrightarrow$ x² - 4x + 3x - 12

$\sf \longrightarrow$ x² - x - 12

Product : x² - x - 12
