Question

*BRAINLIEST* (EASY QA: Warm UP) Find a positive solution to each equation: x2 = 1/4

Answer 1

Answer:

C. x = 1/2

Explanation:

$\sf \rightarrow x^2 = \dfrac{1}{4}$

$\sf \rightarrow x=\sqrt{\dfrac{1}{4}},\:x=-\sqrt{\dfrac{1}{4}}$

$\sf \rightarrow x=\dfrac{1}{2},\:x=-\dfrac{1}{2}$

As asked for positive solution (+)

$\sf \rightarrrow \sf \rightarrow x=\dfrac{1}{2}$

Answer 2

$\qquad\qquad\huge\underline{{\sf Answer}}$

$\textbf{Let's get it solved :}$

• $\sf{x² = \dfrac{1}{4}}$

• $\sf{x = \sqrt{\dfrac{1}{4}}}$

• $\sf{x= \pm{\dfrac{1}{2}}}$

• $\sf{x ={\dfrac{1}{2}} }$
