<span>When we remove those parentheses, the sign of every term
within the parentheses changes.</span>

Problem 2.   Remove the parentheses.

a)   p + (q −r + s) <span>= p + q − r + s</span>

b)   p − (q −r + s) <span>= p − q + r − s</span>

In each of the following problems, remove the parentheses, then simplify
by adding the numbers.

For example,

<span><span><span>(x − 3) − (y − 4)</span>  =  <span>x − 3 − y + 4</span></span> <span>   =  <span>x − y + 1.</span></span></span>

The sign preceding  (x − 3)  is understood to be + . Therefore the signs within those parentheses do not change.

But the sign preceding (y − 4) is minus.  Therefore, y changes to −y, and −4 changes to +4.

Finally, it is the style in algebra to to write the literal terms, x − y, to the left of the numerical term.

Solve for x in the equation X2-8x+41 = 0 -
djverab [1.8K]

Answer:

The value of x fro the given equation is ( 4 + 2 i ) , ( 4 - 2 i )

I.e option D  

Step-by-step explanation:

Given equation as :

x² - 8 x + 41 = 0

For quadratic equation  ax² + b x + c = 0

The value of x = \frac{-b\pm \sqrt{b^{2}-4\times a\times c}}{2\times a}

∴ For equation x² - 8 x + 41 = 0

Or,                x = \frac{8\pm \sqrt{-8^{2}-4\times 1\times 41}}{2\times 1}

Or,                x = \frac{8\pm \sqrt{-100}}{2}

Or,                x = \frac{8\pm 10i}{2}

∴                  x = ( 4 + 2 i ) , ( 4 - 2 i )

Hence The value of x fro the given equation is ( 4 + 2 i ) , ( 4 - 2 i )

I.e option D     Answer
