Prove 2√(x) + 1/√(x + 1) <= 2√(x+1) for all x in [0,inf)

EleoNora [17]

Start by multiplying each side of the inequality by $\sqrt{x + 1}$ and simplifying:

$2 \sqrt x + \frac{1}{\sqrt{x+1}} \leq 2 \sqrt{x + 1}$
$(2 \sqrt x + \frac{1}{\sqrt{x+1}})(\sqrt{x + 1}) \leq (2 \sqrt{x + 1})(\sqrt{x + 1})$
$2 \sqrt{x(x + 1)} + 1 \leq 2(x + 1)$
$2 \sqrt{x^2 + x} + 1 \leq 2x + 2$
$2 \sqrt{x^2 + x} \leq 2x + 1$
$\sqrt{x^2 + x} \leq x + \frac{1}{2}$

From here, we can square both sides to get

$x^2 + x \leq (x + \frac{1}{2})^2$
$x^2 + x \leq x^2 + x + \frac{1}{4}$
$0 \leq \frac{1}{4}$ , which is always true.

Can I please get some help on 2 and 4

lakkis [162]

Answer:

2. Equivalent

4. Denominator

Step-by-step explanation:

2. To subtract unlike fractions, rewrite them as Equivalent fractions with the same denominator. This is true because when we want to add or subtract fractions with different denominators, we can multiply them until they have the same denominator, which allows us to easily subtract.

4. Fractions with equal numerators and Denominators are equivalent to 1. This is also true, since 4/4 is a whole number, and that is the case with any fraction that has the same numerator and denominator

Hope this helps! :D
