Solve for x in the equation x squared + 2 x + 1 = 17.

Whitepunk [10]

Answer:

x = negative 1 plus-or-minus StartRoot 17 EndRoot

Step-by-step explanation:

Given:

$x^2+2x+1=17$

We need to solve for x.

$x^2+2x+1=17 \ \ \ \ equation\ 1$

First we will solve L.H.S

Factorizing the equation we get;

$x^2+2x+1\\=x^2+x+x+1\\=x(x+1)+1(x+1)\\=(x+1)(x+1)\\=(x+1)^2$

Now Things which are equal to the same thing are also equal to one another. Since

$x^2+2x+1=17$

$x^2+2x+1=(x+1)^2$

then, according to the law of transitivity,

$(x+1)^2=17$

Now, applying the Square Root Principle we get:

$\sqrt{(x+1)^2} =\sqrt{17}$

Now Square root and square gets cancelled.

$x+1=\sqrt{17} \\x=-1+\sqrt{17}$

Since a square root has two values, one positive and the other negative.

$x=-1\±\sqrt{17}$

Hence Final Answer is $x=-1\±\sqrt{17}$ .

Benny opened a bank account. He deposited $92.50 into his account every month for 10 months. He used $36.50 every month to pay f

neonofarm [45]

$92.50 * 10 =$925 ( deposited$92.50 into his account every month for 10 so we multiply)
$36.50*10 = $365 ( used $36.50 every month to pay art lessons every month means he took out)
925-365=560 ( total amt left in the account after taking out $365)
He used 1 over 2 of total money means
560/2 = 280

The answer would be B $280.

Hope this helps!!
