+82 For the following system of equations: { -4x2+2x+5
{ 2x2-3x+6
a) algebraically determine the solution(s)
b) Verify that your solution(s) statisfy both equations
+118608 Hi Julia,
These are not equations. there are not equal signs. They need y= or f(x)= or some other funtion name =
I will assume they are f(x)= and g(x)=
a) f(x)=g(x) then
-4x2+2x+5=2x2-3x+6
now solve them simultaneously.
b) plug the answers that you get into the original equation to see if they make f(x) and g(x) equal
You can also put the equations into Desmos graphing calc to see where they both cross.
For the calc call them both y=

+82 I did it myself and the answer was X= 1/2 and X= 1/3.
I verified it and it is true for both equations.
I posted here because I thought it looked too hard for me at first to do by myself but then I fgured it out. Thank you.
+118608 You're welcome Julia.
You should get used to plugging you equations into Desmos AFTER you have solved them yourself.
This will increase your understanding of how the algebra and the graphical representations relate to each other.
You will enhance your learning enormously.
