Question

factor x/2 - 6x - 40

Answer 1

x/2-6x-40

Step-by-step explanation:

x/2-6x-40

x(1/2-6-40)

x(1*1/2-6*2/2-40*2/2)

x(1/2-12/2-80/2)

x(67/2)

x=33.5

Answer 2

Step-by-step explanation:

$\frac{x}{2} - 6x - 40$

a - x/2, b - 6x, c - 40

Solution :

Formula -

• a - b - c = a² - b² - c² - 2ab - 2bc - 2ac

$={ \frac{x}{2} }^{2} - {6x}^{2} - {40 }^{2} - 2 \times \frac{x}{2} \\ \times 6x \times 2 \times 6x \times 40 \times 2 \times 40 \times \\ \frac{x}{2}$

$\frac{ {x}^{2} }{4} - 36x^{2} - 1600 - 6x - 240 - \frac{40x}{2}$
