Simplify by combining like terms 3a+y-5y+6a

Hello  Lobsterquake365

Combining like terms for this problem would be split into two.

Since there are only two variables.

a and y

3a can only go into 6a, for that part would be 9a

y can only go into 5y, for that part being -4y

So our final equation would be

-4y + 9a

:)

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
