Δ=17^2-4×5×6=0

289-120=169

x1,2= - 17/10 +or- 13/10

x1,2=-30/10= - 3
Or
x1,2=-4/10 = - 2/5

What is 1 7/8 Times 2 1\3

slamgirl [31]

We need to convert the mixed fractions into improper fractions.

1*8 = 8
8+7 = 15

15/8

2*3 = 6
6+1 = 7

7/3

Now we can finish and multiply

$\frac{15*7}{8*3}$

15*7 = 105
8*3 = 24

Simplify 105/24

105/24

24*4 = 96

105 - 96 = 9

4 is the whole number, and 9 is the numerator.

4 9/24

Simplify that,

9/3 = 3
24/3 = 8

4 3/8

Answer: $4\frac{3}{8}$
