Extended Problems, Extraneous Solutions

diamong [38]

Answer:

1a. 2 is the solution

1b. -3 is because square root of 1 doesn't equal -1.

1c.-3

Step-by-step explanation:

1.

$(x + 2 = \sqrt{3x + 10}$

Square both sides

$(x + 2) {}^{2} = 3x + 10$

Remeber perfect square Rule

$(x + y) {}^{2} = {x}^{2} + 2xy + {y}^{2}$

So now we got

$x {}^{2} + 4x + 4 = 3x + 10$

${x}^{2} + x + 4 = 10$

${x}^{2} + x - 6 = 0$

Factor into binomial.

$(x + 3)(x - 2) = 0$

So our solution is 3 or 2. However, let's check our work.

$- 3 + 2 = \sqrt{3( - 3) + 10}$

$- 1 = \sqrt{1}$

However square root of 1 is 1. It could be 1 but in Math, <em>We</em><em> </em><em>only</em><em> </em><em>take</em><em> </em><em>the</em><em> </em><em>principal</em><em> </em><em>square</em><em> </em><em>root</em><em> </em><em>which</em><em> </em><em>is</em><em> </em><em> </em><em>positive</em><em> </em><em>always</em><em>.</em><em> </em><em>So</em><em> </em><em>-3</em><em> </em><em>isn't</em><em> </em><em>a</em><em> </em><em>solution</em><em>.</em>

<em>So</em><em> </em><em>let</em><em> </em><em>try</em><em> </em><em>2</em><em>.</em>

<em> $2 + 2 = \sqrt{3(2) + 10} = 4 = \sqrt{16} = 4 = 4$ </em>

<em>So</em><em> </em><em>this</em><em> </em><em>is</em><em> </em><em>indeed</em><em> </em><em>the</em><em> </em><em>solution</em><em>.</em>

<em>Make</em><em> </em><em>up</em><em> </em><em>equation</em><em> </em><em>for</em><em> </em><em>2</em><em> </em><em>and</em><em> </em><em>3</em><em>.</em><em> </em><em>Ask</em><em> </em><em>me</em><em> </em><em>if</em><em> </em><em>you</em><em> </em><em>need</em><em> </em><em>help</em><em>.</em>
