Question

What are the solutions of 2x2 + 3x = −5? (6 points)

the quantity negative 3 plus or minus i square root of 31 all over 4

the quantity negative 3 plus or minus 7i all over 4

the quantity negative 3 plus or minus i square root of 19 all over 4

Answer 1

step one:
2by2 goes first,so we get 4.
4+3x=-5
step two:
we remove 4 to the other side so we leave 3x alone, and when +4 is removed, it becomes negative.
3x=-5-4
so 3x=-9
step three:
-9 is divided by 3 so the answer is -3

Answer 2

i got x = -.3 repeating. 2x2 = 4 + 3x=-5 u then -4 from each side  and you get 3x = -1. divide both sides by 3 and you get x= -.3 repeating.
