Answer 2

Answer:

1. a) |-3|-|-5| = 3-5=-2

b) √ |8|-|-4|-|4| = √ ( 8-8) = √ 0 = 0

c) | (-4)×(-2)|-|-6| = 8 - 6 = 2

2.

Let f(x) =2x^2 +7x - 4

Then

f(2) =2×2^2 +7×2 - 4 = 8 +14-4 = 18 # 0

f(3) =2×3^2 +7×3 - 4 = 18 +21-4 = 35 # 0

f(-4) =2×(-4)^2 +7×(-4) - 4 = 32 - 28 -4 = 0

So - 4 is a zero of 2x^2 +7x - 4
