Which graph represents the solution set for the quadratic inequality x2 + 2x + 1 > 0

AnnyKZ [126]

we have

$x^{2}+2x + 1 > 0$

we know that

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

$(x+1)^{2}> 0$

two solutions

<u>first solution </u>

$(x+1)> 0$

$x > -1$

the first solution is the interval---------> (-1,∞)

<u>second solution</u>

$-(x+1)> 0$

$-x-1> 0$

$-x> 1$

$x< -1$

the second solution is the interval---------> (-∞,-1)

therefore

the solution is all real numbers except the number $-1$

Which choice is equivalent to the quotient shown here when x is greater than or equal to 0?

Dima020 [189]

Answer: OPTION C

Step-by-step explanation:

Remember that:

$\sqrt[n]{a^n}=a$

And the Product of powers property establishes that:

$a^m*a^n=a^{(mn)}$

Rewrite the expression:

$\frac{\sqrt{18x} }{\sqrt{32} }$

Descompose 18 and 32 into their prime factors:

$18=2*3*3=2*3^2\\32=2*2*2*2*2=2^5=2^4*2$

Substitute into the expression, then:

$\frac{\sqrt{(2*3^2)x} }{\sqrt{2^4*2} }$

Finally,simplifying, you get:

$\frac{3\sqrt{(2)x} }{2^2\sqrt{2} }=\frac{3\sqrt{2x}}{4\sqrt{2}}=\frac{(3)(\sqrt{x})(\sqrt{2})}{(4)(\sqrt{2})}= \frac{3\sqrt{x}}{4}$
