Question

Find the discriminant of the following equation.
4x2 + 16x + 16 = 0

Answer 1

the generic form of a quadratic is: ax^2 +bx + c

where the discriminant is: b^2 -4ac

Answer 2

i cant recall if you gotta factor out that 4 first or not

Answer 3

0

Answer 4

the wolf says it 0 so lets see :)

16^2 -4(16)(4) = 4^2-4(4)

(4^2)^2 -4(4)(4)(4)-4^2 +4(4) = 0

4^4 - 4^4 = 0 ; guess it doesnt matter if you factor or not :)

Answer 5

factored might make the numbers smaller to manage better tho

Answer 6

4^2 - 4(4) = 0 ; so discriminant is 0 ;)

Answer 7

16^2-4*4*16=0
