Factor the perfect square trinomial.<br> x(Squared)+4x+4

Nataliya [291]

Answer:

(x + 2)²

Step-by-step explanation:

Given

x² + 4x + 4 ← is a perfect square of the form

(x + a)² = x² + 2ax + a²

Compare like terms

a² = 4 ⇒ a = $\sqrt{4}$ = 2, thus

x² + 4x + 4 = (x + 2)²

What is 7 1 / 5 - 6 2/5

Lunna [17]

$7\dfrac{1}{5}=\dfrac{7\cdot5+1}{5}=\dfrac{35+1}{5}=\dfrac{36}{5}\\\\6\dfrac{2}{5}=\dfrac{6\cdot5+2}{5}=\dfrac{30+2}{5}=\dfrac{32}{5}\\\\7\dfrac{1}{5}-6\dfrac{2}{5}=\dfrac{36}{5}-\dfrac{32}{5}=\dfrac{36-32}{5}=\boxed{\dfrac{4}{5}}$

$7\dfrac{1}{5}-6\dfrac{2}{5}=(7-6)+\left(\dfrac{1}{5}-\dfrac{2}{5}\right)=1+\dfrac{1-2}{5}=1+\dfrac{-1}{5}=1-\dfrac{1}{5}\\\\=\dfrac{5}{5}-\dfrac{1}{5}=\dfrac{5-1}{5}=\boxed{\frac{4}{5}}$
