Algebra:

FOR EXAMPLE: 2= 5-x

u can move 5 to the other side and it will become 2-5 = -3

so -x=-3 therefore x=3, B

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11

two? xd
