Step-by-step explanation:
The distance in feet that Karina swims in a race is represented by 4d - 4, where is d is the distance for each lap.
To get equivalent expression we factor the expression 4d-4
Greatest common factor is 4
Factor out 4 from the expression 4d-4

The equivalent expression for is
Answer:
Step-by-step explanation:
The discriminant is found in
which is part of the quadratic formula. In
, a = 4, b = 10, c = -16. Filling in for the discriminant:
It's positive so we know we have real roots; it's not a perfect square, so our solutions are 2 complex rational.
In , a = -16, b = -7, c = 3. Filling in for the discriminant:
It's positive and not a perfect square so the 2 solutions are complex rational
