Question

One of the factors of (25x - 1) = (1 + 5x) is
(A) 5 x
(B) 5 -
(C) 5x - 1
(D) 10%
$263 - .3x > y \times = y - - x = {y363\pi\pi \binom{\pi\pie. = { < kf \times \frac{?}{?} }^{?} }{?} }^{2}$
​

Answer 1

Answer:

Now, (25x2 -1) + (1 + 5x)2

= 25x2 -1 + 1 + 25x2 + 10x [using identity, (a + b)2 = a2 + b2 + 2ab]

= 50x2 + 10x = 10x (5x+ 1)

Hence, one of the factor of given polynomial is 10x.

Answer 2

Step-by-step explanation:

25X - 5X = 1 + 1

X = 2/20 =

${10}^{ - 1}$

So Answer is C)

${5x}^{ - 1}$
