x2 + 4x = 0
⇒ x(x + 4) = 0
⇒ x = 0 or x = -4
-4x + 9y = 0 is the equation of a line in the Cartesian plane and the coordinates of any of the infinite number of points on that line will satisfy the equation.
2y = 4x + 3At the x-intercept, y=0.0 = 4x + 34x = -3x = -3/4The coordinates of the point are (-3/4 , 0)
4x + 2(3x) = 30 10x = 30 x= 3. Y= 9. (3,9)

No real roots. Imaginary roots as this function does not intersect the X axis.
y = x2-4x+4 Since the highest degree term is 2, it must have 2 roots
4x + 2(3x) = 30 10x = 30 x= 3. Y= 9. (3,9)

No real roots.
The answer to the problem of 13 equals -4x plus 9 is x equals -1.
x2-4x+4 = 0 (x-2)(x-2) = 0 x = 2 or x = 2 It has two equal roots.
4x plus 7 plus 3x equals 19 plus xx = 2
