<span>1. 3a²-a = a(3a - 1)
2. 7ab³-14b = 7b(ab^2 - 2)
3. x³-x²+x = x(x^2 - x + 1)
4. 12x³-xy² = x(12x^2 - y^2)
5. 5x-6x²+7x³ = x(5 - 6x + 7x^2)
6. 7a+8ab+9a² = a(7 + 8b + 9a)

</span>= 3x(x - y + 2y^2)
Answer:
x = 2
y = -5
Step-by-step explanation:
2x - y = 9
y = x - 7
2x - y = 9
2x - (x - 7) = 9
2x - x + 7 = 9
x + 7 = 9
x = 2
y = x - 7
y = 2 - 7
y = -5
X does not equal one but there is 1x in the problem so it is 1.
So.. to complete the square you always take 1/2 of that number.
so
half of 1 is 1/2.
Then you square that number 1/2 * 1/2 = 1/4
