Calculate a and b if

const2013 [10]

Notice that

$7^{2014} - 7^{2012} = 7^{2012} \bigg(7^2 - 1\bigg) = 7^{2012} \times 48 = 2^4 \times 3 \times 7^{2012}$

$12=2^2\times3$ , so

$\dfrac{7^{2014}-7^{2012}}{12} = 2^2 \times 7^{2012}$

Then taking the positive square root gives

$\sqrt{\dfrac{7^{2014}-7^{2012}}{12}} = \sqrt{2^2 \times 7^{2012}} = 2\times7^{1006}$

so $\boxed{a=2}$ and $\boxed{b=1006}$ .

Svetlanka [38]

Answer:

<h3> $\boxed{ \boxed{ \bold{ {x}^{2} + 4x - 21}}}$ </h3>

Step-by-step explanation:

$\sf{(x - 3)(x + 7)}$

Use the distributive property to multiply each term of the first binomial by each term of the second binomial.

⇒ $\sf{x(x + 7) - 3(x + 7)}$

⇒ $\sf{ {x}^{2} + 7x - 3x - 21}$

Collect like terms

⇒ $\sf{ {x}^{2} + 4x - 21}$

Hope I helped!

Best regards!!
