Answer:
1. y = (x + 4)(x + 2)(x - 1)(x - 3)
x = -4
= (-4 + 4)(-4 + 2)(-4 - 1)(-4 - 3)
= (0)(-2)(-5)(-7)
= (0)(-5)(-7)
= (0)(-7)
x = -2
= (-2 + 4)(-2 + 2)(-2 - 1)(-2 - 3)
= (2)(0)(-3)(-5)
= (0)(-3)(-5)
= (0)(-5)
x = 0
= (0 + 4)(0 + 2)(0 - 1)(0 - 3)
= (4)(2)(-1)(-3)
= (8)(-1)(-3)
= (-8)(-3)
x = 1
= (1 + 4)(1 + 2)(1 - 1)(1 - 3)
= (5)(3)(0)(-2)
= (15)(0)(-2)
= (0)(-2)
x = 2
= (2 + 4)(2 + 2)(2 - 1)(2 - 3)
= (6)(4)(1)(-1)
= (24)(1)(-1)
= (24)(-1)
2. y = (x - 5)(x + 1)(x - 3)(x + 2)
x = -3
= (-3 - 5)(-3 + 1)(-3 - 3)(-3 + 2)
= (-8)(-2)(-6)(-1)
= (16)(-6)(-1)
= (-96)(-1)
= (-2 - 5)(-2 + 1)(-2 - 3)(-2 + 2)
= (-7)(-1)(-5)(0)
= (7)(-5)(0)
= (-35)(0)
= (0 - 5)(0 + 1)(0 - 3)(0 + 2)
= (-5)(1)(-3)(2)
= (-5)(-3)(2)
= (15)(2)
= (1 - 5)(1 + 1)(1 - 3)(1 + 2)
= (-4)(2)(-2)(3)
= (-8)(-2)(3)
= (16)(3)
x = 3
= (3 - 5)(3 + 1)(3 - 3)(3 + 2)
= (-2)(4)(0)(5)
= (-8)(0)(5)
= (0)(5)
