Answer:
(x-2)(x+4)
Step-by-step explanation:
x² + 2x - 8 = x² + 2x +1 - 9 = x² + x +x+1 - 9 = x(x+1) +(x+1) - 9
= -
= (x+1-3)(x+1+3)
= (x-2)(x+4)
2 corners are both 45 degrees, meaning that they are both the same length.
For this we use the pythagorean theorem, but a bit modified:
a^2 + a^2 = c^2
2a^2 = 256
Solve for a:
a^2 = 128
a = 8 √2
One leg is equal to √128 or 8 √2.

Answer:
3( n + )² - = 0
Step-by-step explanation:
3n² = 6 - 17n ⇔ 3n² + 17n - 6 = 0
3( n² + 2 × n + ( )² - ( )² - 2 ) = 0
3( n + )² - 3 × - 6 = 0
3( n + )² - = 0
