The solution to the given system of equation in coordinate form if both equations are equal to each other is (-1, 5)

How to solve system of equations

Given the system of equations

y = 2x² + 6x + 1

y = −4x² + 1

Equate both expressions to have:

2x² + 6x + 1 = −4x² + 1

Equate to zero

2x² + 6x + 1  +4x² - 1

6x² + 6x = 0

6x² = -6x

x = -1

Recall that y = −4(-1)² + 1

y = 4 + 1 = 5

Hence the solution to the system of equation is (-1, 5)
