(picture) multiplying polynomials and simplifying expressions

Step-by-step explanation:

we multiply 3a+2 inside the parenthesis to find the product

first multiply 3a inside second parenthesis

now multiply +2 inside second parenthesis

Now we combine it

combine like terms

step-by-step explanation:

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
