X² + 6x + 5 = y
- Figure out the coefficient :
a= 1, b= 6 c=5
- Use the Quadratic formula :
X= -b /2a = -6/2 x 1 = -3
X= -3
- a = 1, b = 6 and c = 5 so we would have the equation, y = x2 + 6x + 5. substitute the same values in for x .
x | y = x2 + 6x + 5 | (x, y) |
-5 | (-5)2 + 6(-5) +5 | (-5, 0) |
-4 | (-4)2 + 6(-4) +5 | (-4, -3) |
-3 | (-3)2 + 6(-3) +5 | (-3, -4) |
-2 | (-2)2 + 6(-2) +5 | (-2, -3) |
-1 | (-1)2 + 6(-1) +5 | (-1, 0) |
- Finally Graph :
