5a2-60a+180

5 (a2 - 12a + 36)

5 (a2 - 6a - 6a +36)

5 ( a(a - 6) -6( a- 6)

5 (a-6)(a-6)

5(a-6)^2

s2 - 256

s2 - 16^2

Answer:

Step-by-step explanation:

a² - 12a + 36 = a² + 2*a *6 + 6²

Compare with (x -y)² = x²- 2ab + y²

                      = (a - 6)²

5a² - 60a + 180 = 5 *a² - 5 * 12 * a + 5 * 36

                        =  5 (a² - 12a + 36)

                        =  5 (a - 6)²

256 = 16 * 16 = 16²

a² - b² = (a + b)(a - b)

s² - 256 = s² - 16²

             = (s + 16) (s - 16)

49q² + 42qr + 9r² = 7²q² + 2 * (7q)  * 3r + 3²r²

                              = (7q)² + 2 *7q * 3r  +(3r)²

                              = (7q + 3r)²

LekaFEV [45]

<em>Answer:</em>

<em>The solution is (5, −2)</em>

<em>Step-by-step explanation : </em>

<em>x + y = 3 => y = 3 - x</em>

<em>                   y = x - 7  } => </em>

<em>=> 3 - x = x - 7 => 3 + 7 = x + x => 2x = 10 => </em><em>x = 5</em>

<em />

<em>x + y = 3</em>

<em>5 + y = 3</em>

<em>y = 3 - 5</em>

<em>y = - 2</em>
