How to solve the problem <br> Step by step
Butoxors [25]
Let's solve this problem step-by-step.

STEP-BY-STEP SOLUTION:

= 1 / 8 + ( - 5 / 12 ) - 3 / 8

= 1 / 8 - 5 / 12 - 3 / 8

= ( 3 - 10 - 9 ) / 24

= - 16 / 24

= - 2 / 3

Hope this helps! <3

What are the possible values of x in 8x2 + 4x = -1?
Rudiy27
Answer: x only can have complex values, not real values.


x = -1/4 - 1/4i and x = -1/4 + 1/4 i


Explanation:


Finding the possible values of x in the expression given is solving the quadratic equation.


8x² + 4x = - 1

Rearrange the terms:


8 (x² + x/2) = - 1 ← common factor 8 in the left side


x² + x/2 = - 1/8 ← division property

x² + x/2 + 1/16 = - 1/8 + 1/16 ← addition property

(x + 1/4)² = -1/8 + 1/16 ← -factor the perfect square trinomial in the left side


(x + 1/4)² = - 1/16 ← add the fractions in the right side


x + 1/4 = (+/-) √ (-1/16) ← square roots on both sides


x + 1/4 = (+/-) (1/4)i ← complex solution


x = - 1/4 +/- 1/4i


x = - 1/4 - 1/4i and x = - 1/4 + 1/4 i ← answer
