Question

Find all real solutions of the equation: x 2 + 3x − 10 = 0

Answer 1

8/3

Explanation:

2 +3x + 10 = 0

2-10 +3x = 0

-8 + 3x = 0

3x = 8

x = 8/3

Answer 2

Answer: x=8/3 or x= 2.6666....

Explanation:

`2+3x-10=0`

`2-10=-8`

`3x-8=0`

add 8 on both sides

`3x-8+8=0+8`

`3x=8`

divide 3 on both sides

`x=(8)/(3)`
