Respuesta :
combining like terms gives us
5x^2 - x + 9 = -y
multiplying by -1 on both sides:
y = -5x^2 + x - 9
discriminant = b^2 - 4ac = 1^2 - 4(-5)(-9) which is negative so no solution
5x^2 - x + 9 = -y
multiplying by -1 on both sides:
y = -5x^2 + x - 9
discriminant = b^2 - 4ac = 1^2 - 4(-5)(-9) which is negative so no solution
