Factorize (4d-3e)2 +6d(4d-3e)​
Natasha_Volkova [10]

Answer:

(4d - 3e)(10d - 3e)

Step-by-step explanation:

(4d - 3e)² + 6d(4d - 3e) ← factor out (4d - 3e) from each term

= (4d - 3e)(4d - 3e + 6d) ← collect like terms inside parenthesis

= (4d - 3e)(10d - 3e)

Prove that root 7 is irrational by the method of contradiction
Alchen [17]

Let assume that \sqrt7 is a rational number. Therefore it can be expressed as a fraction \dfrac{a}{b} wherea,b\in\mathbb{Z} and \text{gcd}(a,b)=1.

\sqrt7=\dfrac{a}{b}\\\\7=\dfrac{a^2}{b^2}\\\\a^2=7b^2

This means that a^2 is divisible by 7, and therefore also a is divisible by 7.

So, a=7k where k\in\mathbb{Z}

(7k)^2=7b^2\\\\49k^2=7b^2\\\\7k^2=b^2

Analogically to a^2=7b^2 ------- b^2 is divisible by 7 and therefore so is b.

But if both numbers a and b are divisible by 7, then \text{gcd}(a,b)=7 which contradicts our earlier assumption that \text{gcd}(a,b)=1.

Therefore \sqrt7 is an irrational number.
