Answer:
Step-by-step explanation:
The function is f(x) = -4x²+10x-8
Let Δ be our the dicriminant
- Δ= b²-4ac
- b = 10
- a = -4
- c = -8
- Δ = 10²-4*(-4)(-8)
- Δ = 100-128
- Δ = -28
The value of the discriminant is -28 and since it is negative this function has no real zeroes
Answer:

Step-by-step explanation:
Given:


Required:
LCM of the polynomials
SOLUTION:
Step 1: Factorise each polynomial








Step 2: find the product of each factor that is common in both polynomials.
We have the following,

The common factors would be: =>
(this is common in both polynomials, so we would take just one of them as a factor.
and,

Their product =
