MA_775_DIABLO [31]

Answer:

Add 4 on both sides.

In the equation there is a -4.

If -4+4=0, that is how you would get rid of the -4.

But, you need to add 4 to 29 to really get rid of the -4.

So, 29+4 is 33.

b=33

Asap!!<br> 85=2x(x^2+3)(2x+5) use quadratic equation

emmainna [20.7K]

Answer:

Step-by-step explanation:

85=2x(x^2+3)(2x+5)

85=2x(2x^3+5x^2+6x+15)

85=4x^4+10x^3+12x^2+30x

4x^4+10x^3+12x^2+30x-85=0

2x^2(2x^2+5x+6)+30x-85=0

shoot, this isn't possible with quadratic, maybe you can get somewhere from here
