(5x - 6) (5x - 6)?

Question

perform the indicated operation

Answer 1

(5x - 6)(5x - 6)
= (5x)(5x) + (5x)(-6) + (-6)(5x) + (-6)(-6)
= 25x^2 - 30x - 30x + 36
= 25x^2 - 60x + 36

Answer 2

We can either use the "FOIL" method, or we can use the formula
(a - b)^2 = a^2 - 2ab + b^2
In this case
a = 5x
b = 6

So plugging into the formula

(5x - 6)^2 = (5x)^2 - 2(5x)(6) + (6)^2
= 25x^2 - 60x + 36


Or we can solve this using FOIL
First: 5x * 5x = 25x^2
Outer = 5x(-6) = -30x
Inner = -6(5x) = -30x
Last = (-6)(-6) = 36

Putting it all together we get
25x^2 - 60x + 36


Either way, 25x^2 - 60x + 36 is your answer

Answer 3

i totally know this one:
First Outer Inner Last = FOIL
first
5x times 5x equals to 25x^2 ( ^2 means squared)
outer
5x times -6 equals to -30x (negative 30x)
inner
-6 times 5x equals to -30x (negative 30x)
last
-6 times -6 equals to 36
(two negatives make one positive)

then you add up all four of the answers from above (combine like terms) (like terms mean similiar terms)

25x^2 + -30x + -30x + 36
combine -30x with -30x and you get -60x
youcan't combine anything else so you get for your final answer: 25x^2 - 60x -36

YOU'RE WELCOME HAVE A GREAT DAY!!!

Answer 4

(5x-6)(5x-6)

Use the FOIL method:

Front (5x)(5x)=25x^2
Outside (5x)(-6)= -30x
Inside (-6)(5x)= -30x
Last (-6)(-6)=36

25x^2 - 60x + 36

Answer 5

(5x-6)(5x-6)
=5x(5x-6) + -6(5x-6)
2
=25x -30x-30x+36
2
=25x -60x+36

Answer 6

Answer: 25x^2 - 60x + 36

Answer 7

25x^2 - 60x + 36

Answer 8

25x^2-60x+36
Just remember (a-b)(a-b) = (a-b)^2 = a^2-2ab+b^2

Answer 9

(5x)²+(5x)(-6)+(5x)(-6)+(-6)²
25x²-30x-30x+36
25x²-60x+36

Answer 10

25x^2-30x-30x+36
25x^2-60x+36
satisfied?!
