It is 2.
3 + -3
(0, -3)
a = 3 and y = 0
-2 -1 0 1 2
It is 2.
3 + -3
(0, -3)
Zero
a = 3 and y = 0
x = 0
-2 -1 0 1 2
Oh, dude, it's like so simple. 0 plus 3 equals 3. I mean, come on, even a potato could figure that one out.
2x^2 + 8x + 3 = 0
x2 plus 3x plus 3 is equals to 0 can be solved by getting the roots.
(2x + 1)(x + 3) = 0; x = -0.5 or -3
(1, 0)
