Question

Solution set of equation 4x² – 16 = 0;​

Answer 1

Answer:

+2

Step-by-step explanation:

4x2−16 fits the difference of squares property

a2−b2, which can be factored as (a+b)(a−b)

Here, we can take the square root of 4x2, which is 2x and we can take the square root of 16 which is ±4.

Thus, a=2x and b=±4, so we have

(2x+4)(2x−4)=0

We can factor a 2 out of both expressions to get

2(x+2)(x−2)

Setting the factors equal to zero, we get

x=±2

Hope this helps!
