Answer: x= -5/4, -1/2
Step-by-step explanation:
10x^2+15x-9=2x^2+x-14
- Move all terms to one side.
10x^2+15x−9−[tex]2x^{2}[/tex]−x+14=0
- Simplify 10x^2+15x−9−[tex]2x^{2}[/tex]−x+14 to 8x^2+14x+5.
8x^2+14x+5.
- Split the second term in 8x^2+14x+5 into two terms.
[tex]8x^{2}+10x+4x+5=0[/tex]
- Factor out common terms in the first two terms, then in the last two terms.
2x(4x+5)+(4x+5)=0
- Factor out the common term 4x+5.
(4x+5)(2x+1)=0
- Solve for x.
x= -5/4, -1/2
Hope this helps, have a BLESSED and wonderful day, as well as a safe one! Also, hope your having a good 2020 :-)
