Can a negative number be a solution to a square root

1 answer:

4 0

A square root of any number greater than 0 always has two answers, one positive and one negative.
Squareroot (36) = 6 or -6.
Since 6×6=36 and -6×-6=36.
Squareroot (0)= just 0 because there is no negative 0 (:

How can we get Equation B from Equation A? A. 5 = -2 (x - 1) B. 5 = -2x + 2 How can we get Equation B from Equation A?

lesya [120]

Answer:

Please check the explanation.

Step-by-step explanation:

<u>Determining equation B from Equation A</u>

Given the equation A

$5\:=\:-2\:\left(x\:-\:1\right)$

Apply distributive law $a\left(b-c\right)=ab-ac$

$5= -2x+2$ which is equation B

Hence, equation B can be obtained by implementing the distributive law operation on equation A.

<u>Determining equation A from Equation B</u>

Given the equation B

$5 = -2x + 2$

Factor out common term -2 on the right-hand side of the equation

$5=-2\left(x-1\right)$ which is the equation A

Hence, equation A can be obtained by factoring out the common term -2 on the right-hand side of equation B.
