[a+b]2 = [a+b]*[a+b]
= a*a + a*b + b*a + b*b
= a2 + 2ab + b2
... which is 2x + 2 = x so x = -2
Insufficient information to solve equation, however it can be simplified. Assuming it looks like this 2 (3y+6) The simplified version would be 6y+12
7C MINUS bracket open c plus 2 bracket close equals 7c minus c minus 2 equals 6c minus 2
The correct ansewer is 8
-8 (U could just have used the numbers rather than spelling it out u know)

(x-2)(x+2)= x2+2x-2x-4= x2-4
4(2x - 3) + 3(2x + 2) 8x - 12 + 6x + 6 14x - 6
4{3x-2}2=36 12x-8=18 12x=26 x=2.16666... I hope I read that equation right. If not, just message me and I can fix it.

The equation is y + 2 = 12.
2(2*4-5)+6 = 12
