Answer:
x= -5, 2
Step-by-step explanation:
set them equal to each other: [tex]x^{2}+5x-9=2x+1[/tex]
subtract 2x from both sides: [tex]x^{2} +3x-9=1[/tex]
subtract 1 from both sides to make it equal to zero: [tex]x^{2} +3x-10=0[/tex]
find which 2 factors of -10 equal 3: 5 and -2
plug it into: [tex](x +?)[/tex]: [tex](x+5) (x -2)[/tex]
set both equations to zero: [tex]x +5=0[/tex] [tex]x-2=0[/tex]
solve: {x| x=-5, 2}
