Given the trinomial 2x2 + 4x + 4, predict the type of solutions.

solutions are not real

Step-by-step explanation:

Use the discriminant to determine the type of solutions

Given ax² + bx + c, then the discriminant is

Δ = b² - 4ac

• If b² - 4ac > 0 then solutions are real and distinct

• If b² - 4ac = 0 then solutions are real and equal

• If b² - 4ac < 0 then solutions are not real

For 2x² + 4x + 4

with a = 2, b = 4 , c = 4 , then

b² - 4ac = 4² - (4 × 2 × 4) = 16 - 32 = - 16

Since b² - 4ac < 0 then solutions are not real

answer: all of the odd numbers were opened

the first person was the one that was opening all of the lockers. since one is odd, this causes all of the odd number lockers to be opened in the end.
