you can use the determinant... to check the solutions or use the general quadratic formula to solve this

@campbell_st is it A, because i got x=-0.43, and x=-2.07 and those arent options.
campbell_st

well you shouldn't have been able to get answers... as the discriminant in this question is \[b^2 - 4ac = 5^2 - 4 \times 2 \times 5 = -15\] and you can't take the square root of a negative number... so you choice of A is correct. but your method is flawed
