Hi
5x²-x-4 = 0
Δ= (-1)² - 4*5*(-4)
Δ = 1 -4*-20
Δ = 1 +80
Δ = 81
√Δ= 9
as Δ ≥ 0 , so 2 solutions exist in R
S1 is : ( 1+9) /2*5 = 10/10 = 1
s2 = (1 -9)/2*5 = -8/10 = -4*2 /2*5 = -4/5
Corrects answers are A and D
X = 12 + 68.
If 68 is 12 less than x, then we should add 12 to 68 to get x.
3 1/100
anything before the dot is considered your whole number and anything after the dot is your fraction
The answer would be 17 just divided 85 by 5 and you'll get your total :)
