(3x - 2)^2 is the same as:

(3x - 2)(3x - 2)

use the FOIL method: First, Outside, Inside, Last

3x(3x) = 9x²
3x(-2) = -6x
-2(3x) = -6x
-2(-2) = 4

9x² - 6x - 6x + 4

Combine like terms

9x² (- 6x - 6x) + 4

9x² - 12x + 4 is your answer

hope this helps

The expression n2 + n represents the total number of blocks used in the nth figure of a pattern. Use the equation n2 + n = 56 to

Brrunno [24]

We have to solve this quadratic equation $n^{2}+n=56$ for n to get <em>which figure has 56 blocks</em>.

$n^{2}+n=56\\n^{2}+n-56=0$

For middle term factorization, we need <em>two numbers that multiplied gives us -56 and added gives us 1 (coefficient of n).</em>

<em>Such two numbers are </em><em>8</em><em> and </em><em>-7</em><em>. We can now write,</em>

<em> $n^{2}+n-56=0\\(n+8)(n-7)=0\\n=-8, 7$ </em>

<u><em>"There is no negative figure number possible, so we disregard -8"</em></u>

Our answer is 7.

ANSWER: The 7th figure has 56 blocks.
