(1.) y = x2 + x - 30
0 = (x + 6)(x - 5)
x + 6 = 0 x - 5 = 0
-6 -6 + 5 +5
x = -6 , x = 5
(ii.) y = 02 + 0 - 30
y = -30
(iii.) y' = 2x + 1
2x + 1 = 0
-1 -1
2x = -1
____ ____
2 2
x = -1/2
0 = (x + 6)(x - 5)
x + 6 = 0 x - 5 = 0
-6 -6 + 5 +5
x = -6 , x = 5
(ii.) y = 02 + 0 - 30
y = -30
(iii.) y' = 2x + 1
2x + 1 = 0
-1 -1
2x = -1
____ ____
