Solve the system using substitution.
Y=-3x^2+x-2,
Y=-5x+3
-5x+3 = -3x^2+x-2
Add 5x and subtract 3 from both sides of the equation. Multiply both sides by -1.
0 = 3x^2 - 6x + 5
However, I don't see how this can be factored. Do you have a typo?
Solving nonlinear systems
To solve this system of equations using substitution, we need to solve one equation for one variable and substitute that expression into the other equation.
Let's solve the second equation for y:
Y = -5x + 3 ...(1)
Now, substitute the expression for Y from equation (1) into the first equation:
-3x^2 + x - 2 = -5x + 3
Next, we rearrange this equation to make it a quadratic equation:
-3x^2 + x + 5x - 2 - 3 = 0
Simplify the equation:
-3x^2 + 6x - 5 = 0
Now, we need to solve this quadratic equation. The standard method to solve a quadratic equation is by factoring, using the quadratic formula, or by completing the square. Once we find the values of x, we can substitute those values back into equation (1) to find the corresponding y-values.
