Question

please solve it I mark it as the brain list.​

Answer 1

Answer:

16x^2 - 25=0

(4x)^2 - (5)^2 = 0

(4×-5)(4x+5)

Therefore x= 5/4 or -5/4.

Answer 2

Answer:

Given equation is

$16 {x}^{2} - 25 = 0$

_________________________________

Given equation can be solved in more than one way.

two ways of solving this equation are shown below

_________________________________

We can solve it to find value of x as:-)

$16 {x}^{2} - 25 = 0 \\ \\ 16 {x}^{2} = 25 \\ \\ {x}^{2} = \dfrac{25}{16} \\ \\ x = \sqrt{ \dfrac{25}{16} } \\ \\ x = \pm \frac{5}{4}$

OR

Given equation can be solved as follow:-)

$16 {x}^{2} - 25 = 0 \\ \\{4x}^{2}-{5}^{2} \\ \\ (4x+5)(4x-5)=0 \\ \\x=\frac{5}{4},\frac{-5}{4}$
