Question

find the following products 1. (x+3)(x-4) 2. ,,(x+4) ( x+6) 3.(a-3) (a-8) 4. ( x-9) ( x+6)​

Answer 1

Step-by-step explanation:

$1. \: (x + 3)(x + 4) \\ x(x + 4) + 3(x + 4) \\ {x}^{2} + 4x + 3x + 12 \\ {x}^{2} + 7x + 12$

$2. \: (x + 4)(x + 6) \\ x (x + 6) + 4(x + 6) \\ {x}^{2} + 6x + 4x + 24 \\ {x}^{2} + 10x + 24$

$3.(a - 3)(a - 8) \\ a(a - 8) - 3(a - 8) \\ {a}^{2} - 8a - 3a + 24 \\ {a}^{2} - 11a + 24$

$4.(x - 9)(x + 6) \\ x(x + 6) - 9(x + 6) \\ {x}^{2} + 6x - 9x - 54 \\ {x}^{2} - 3x - 54$
