Answer:
Step-by-step explanation:
Given Equation:
Taking the terms of 'x' to one side and the constants terms to other side.
On solving the equation the value of 'x' is 3
9^2 - 2^2 = 9*9 - 2*2= 81-4= 77
<span><span> 5n2+10n+20</span> </span>Final result :<span> 5 • (n2 + 2n + 4)
</span>
Reformatting the input :
Changes made to your input should not affect the solution:
(1): "n2" was replaced by "n^2".

</span><span>Step 2 :</span><span>Step 3 :</span>Pulling out like terms :
<span> 3.1 </span> Pull out like factors :
<span> 5n2 + 10n + 20</span> = <span> 5 • (n2 + 2n + 4)</span>
Trying to factor by splitting the middle term
<span> 3.2 </span> Factoring <span> n2 + 2n + 4</span>
The first term is, <span> <span>n2</span> </span> its coefficient is <span> 1 </span>.
The middle term is, <span> +2n </span> its coefficient is <span> 2 </span>.
The last term, "the constant", is <span> +4 </span>
Step-1 : Multiply the coefficient of the first term by the constant <span> <span> 1</span> • 4 = 4</span>
Step-2 : Find two factors of 4 whose sum equals the coefficient of the middle term, which is <span> 2 </span>.
<span><span> -4 + -1 = -5</span><span> -2 + -2 = -4</span><span> -1 + -4 = -5</span><span> 1 + 4 = 5</span><span> 2 + 2 = 4</span><span> 4 + 1 = 5</span></span>
