Question

middle term splitting
(d) x2–2x-8 (NCERT)​

Answer 1

$\large\mathbf\orange{ANSWER \: :}$

x² - 2x - 8 = x² - 4x + 2x - 8 = 0

(x² - 4x) + (2x - 8) = 0

x( x - 4) + 2 ( x - 4) = 0

(x + 2) (x - 4) = 0

Thus, (x + 2) = 0 or (x - 4) = 0

So, x = (-2) or x = 4.

Answer 2

Answer:

x=-2 or x=4

Step-by-step explanation:

x² - 2x - 8

= x² - 4x + 2x - 8 = 0

=(x² - 4x) + (2x - 8) = 0

=x( x - 4) + 2 ( x - 4) = 0

=(x + 2) (x - 4) = 0

=(x + 2) = 0 or (x - 4) = 0

⇒x = -2 or x = 4.
