Answer:
x= -3+√2 or x= -3-√2 ( answer : A and B )
Step-by-step explanation:
hello :
x²+6x+9 = (x+3)².....identity
x²+6x+9 =2 means : (x+3)²=2
so : (x+3 = √2) or (x+3 = - √2)
so two solutions :
x= -3+√2 or x= -3-√2
The answer is B. 8x+6. You multiple 3 and x+4 then combine like terms
It could be 8 since 8x18= 144 and 144 divided by 2 is 72
