Question

Is this correct?

Answer 1

no the the value 4 in 4x is the sum of the factors...

17 only has 2 factors 17 and 1.... so you can't get them to be 4

Answer 2

Is it 16 then?

Answer 3

-5 is the answer

Answer 4

How?

Answer 5

For a quadratic equation to have real and distinct values, the discriminant must be greater than 0

Answer 6

what are the factors of -5 do they add to 4... the larger factor is positive the smaller negative

Answer 7

If ax^2+bx+c=0 is the eqution, then the discriminant is b^2-4ac

Answer 8

from the given equation we have a=1,b=4,c=c hence 4^2-4*1*c>0 that means c<4. from the given values of c, only -5 is less than 4
