Answer:
it is very simple -5 =(5)(-1)=(x+4)(2x-3).so compare( 5)=(x+4) and (x=1) it can be solved by mind.....(2x^2)+5x-7=0 then
These are the steps.
1. Write out the equation.
2. FInd any whole numbers and put them together and find any variables and put them together, both in parentheses.
3. Solve both equations in parentheses.
4. Divide -5 by 3 to find x. The answer is on step 5.
[tex]1. (2x - 3)(x + 4) = -5\\2. (-3 + 4)(2x + x) = -5\\3. (1)(3x) = -5\\4. 3x = -5\\5. x = -1.66[/tex]
