Solve for x.

8x2−3=2

x=±10√4

x=±10√2

x=±5√2

x=±5√4

8x^2 = 5

x^2 = 5/8

x = sqrt(5/8)

x = sqrt(40)/8

x = 4(sqrt 10)/8

x = + sqrt 10/2

answer is b

Step-by-step explanation:

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer
