In order to see how many real roots it has you have to see what the Δ is
So if Δ>0 then there are 2 real roots
If Δ=0 there is 1 real root
If Δ<0 no real root
And we know that:
Δ=b^2-4ac
So in the equation: Δ=b^2+4 and b^2 is always a number greater than or equal to 0 so when you add 4 to it, it is always greater than 0
So it has 2 real roots
Answer:
3x+13
Step-by-step explanation:
since all 4 sides of a square are same we can find the length by dividing the perimeter by 4:
(12x+52)/4=3x+13
3x+13
hope this helps
Answer:
Step-by-step explanation:
5x^4 + 10x^3 + 15x
5x ( x^3 + 2x^2 + 3)
