Which equation has two real solutions?

A. x2 = –100
B. 5x2 = 1
C. 6x2 + 17 = 11
D. 7(x2 + 6) = 42

B

Step-by-step explanation:

Let's go through each equation one by one until we find one that satisfies the condition.

Equation A cannot have two real solutions, since the only thing that could make it true is 10i, which is not a real number.

Equation B could have two real solutions, since if you divide both sides by 5 then you will be left with , which has two real solutions of and . Therefore, the answer is B. Hope this helps!
