please help me solve it

Answer 1

I mostly think the answer is -28

Answer 2

Answer:
`x= - (1 - √(57) )/(4) , (1 + √(57) )/(4)`

Explanation:

You first simplify it. You can use the quadratic formula. First, you have to divide by 2.
`x^(2) + (x)/(2) - 7 = 0` Now you can use the formula, so, the answer is
`x= - (1 - √(57) )/(4) , (1 + √(57) )/(4)`
