Answer:

$\frac{4}{3x-4}$

Step-by-step explanation:

The first thing we do to solve this is factor is completley

You can factor out a 4 from the numerator and get

4(3x+4)

The denominator is a difference of squares which means that

(x^2-y^2)=(x-y)(x+y)

which means that 9x^2-16=

(3x-4)(3x+4)

Put these together and get

$\frac{4(3x+4)}{(3x-4)*(3x+4)}$

The 3x+4 cancels out and we get left with

$\frac{4}{3x-4}$

What is the solution to 2sin^(2)x+sinx+1=0

Alexus [3.1K]

Well you can try rewriting it to this

answer is d 270

first start of by factoring and subtracting the 1 into the right side

sin(x) ( 2 sin (x) + 1) = -1

set each one equal to -1

sin( x) = -1 and 2 sin (x) +1 = -1

2 sin (x) = -2
sin ( x) = -1
so therefore we have our final equation

sin ( x ) = - 1 and sin (x) = -1

so then you look in your unit circle and find what coordinate equals -1 in terms of sin x
