The factored form of given expression is:

16x^2(x-3)(x+3)

Step-by-step explanation:

The identity that can be used to factorize the given expression is:

a^2-b^2 = (a+b)(a-b)

Given

16x^4-144x^2

As 16 is a factor of both terms

=16x^2(x^2-9)

Using the identity

=16x^2[(x)^2-(3)^2]\\=16x^2[(x-3)(x+3)]

Hence,

The factored form of given expression is:

16x^2(x-3)(x+3)

Solve for the value of x.
shutvik [7]

Answer:

Step-by-step explanation:

Both angles are supplementary (they add up to 180°)

This means that (10x) + (6x - 12°) = 180°

(10x) + (6x - 12°) = 180°

10x + 6x - 12° = 180°

16x - 12° = 180°

16x = 192°

x = 12°

Hope this helps!
