Hi again :)

(3p +2)(5p-1)
Distribute '
(3p)(5p)+(3p)(-1)+(2p=)(5p)+(2)(-1)
15p² - 3p + 10x - 2
15p² + 7p - 2
Thus, the correct option is : C

(5w+2)(8w+5) It says to use the tab, but I don't know :) so I am using my way :)
Distribute
(5w)(8w)+(5w)(5)+(2)(8w)+(2)(5)
40w² + 25w + 16w + 10
40w² + 41w + 10
Thus, The answer is B

Again, I don't know how to solve it by suing the tab. However, I will use my way :)
(-5y+3)(2y+5)
Distribute
(-5y)(2y)+(-5y)(5)+(3)(2y)+(3)(5)
-10y² - 25y + 6y + 15
-10y² - 19y + 15
Thus, the answer is : D

(6x - 5)(2x - 3)
Distribute
(6x)(2x)+(6x)(-3)+(-5)(2x)+(-5)(-3)
12x² - 18x - 10x + 15
12x² - 28x + 15
The answer is : A


For #12 The answer is : C

Now let's solve #13
(4x -6y³)²
Distribute
(4x)(4x)+(4x)(-6y³)+(-6y³)(4x)+(-6y³)(-6y³)
16x² - 24xy³-24xy³+36y^6
36y^6 - 48xy³ = 16x²

The answer is B


wow, that was a lot of work. Good luck!
