Answer:
Since b^2 -4ac = 256 we have 2 real distinct root roots
Step-by-step explanation:
4x^2+12x=7
We need to subtract 7 to get it in the proper form
4x^2+12x-7=7-7
4x^2+12x-7=0
The discriminant is b^2 -4ac
when the equation is ax^2 +bx+c
so a =4 b=12 and c=-7
(12)^2 - 4(4)(-7)
144 +112
256
If b^2 -4ac > 0 we have 2 real distinct roots
If b^2 -4ac = 0 we have one real root
If b^2 -4ac < 0 we have two complex root
Since b^2 -4ac = 256 we have 2 real distinct root roots
Answer:
-8
Step-by-step explanation:
both 8^-8 and 16^-8+2 equal 5.9605
120/2=60 (sum of both lengths)
4x+4=60
4x=56
x=14
length=46
width=14
Answer:
2 -6
Step-by-step explanation:
watch the video for a Step-by-step explanation its the one right before the question
What two factors of 48 add up to -16? -4 and -12
So the factored form would be (x-4)(x-12)
