Question

answer this question please ​

Answer 1

Answer:

x= either -1 or -8/5

because they said x= (-13±3) /10

so once add 3 with -13 and once minus 3 from -13 then decided by 10.

hope you understood

Answer 2

Step-by-step explanation:

b²-4ac=(13)²-4×5×8

=169-4×5×8

=169-160

= 9

x=-b-+√b²-4ac

=13+-√9

=-13+3/10

x=-13+3/10

x=-10/10

x=-1

or

x=-13-3/10

x=-16/10

x=-8/5
