Can someone please help me?
Ahat [919]
You solve this problem by factoring. After I have factored it, the problem looks like this:

(2x - 5)(x + 1)

Then the first answer would be solved this way:

2x = 5
x = (5/2)

The second answer would be:

x = -1

Hope this helped!

Whats 2(2+2)X3+1234322-16
natita [175]

So we know that 2+2=4 and then we multiply that by 2 and then by X3, where we get 24X. Then we must subtract 16 from 1234322, which is 1234306. So we add 1234306 to 24X and get 24X+1234306 as our answer.

Hope this helps! <3
