(5-6x)^(2)

Reorder the polynomial 5-6x alphabetically from left to right, starting with the highest order term.
(-6x+5)^(2)

Multiply each term in the first group by each term in the second group using the FOIL method. FOIL stands for First Outer Inner Last, and is a method of multiplying two binomials. First, multiply the first two terms in each binomial group. Next, multiply the outer terms in each group, followed by the inner terms. Finally, multiply the last two terms in each group.
(-6x*-6x-6x*5+5*-6x+5*5)

Simplify the FOIL expression by multiplying and combining all like terms.
(36x^(2)-60x+25)

Remove the parenthesis around the expression
36x^(2)-60x+25.
answer:
36x^(2)-60x+25

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

= (5 - 6x) * 5
= 25 - 30x

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

Add the two products:
= 25 - 30x - 30x + 36x^2
= 25 - 60x + 36x^2

Answer: 36x^2 - 60x + 25

the formula is
(a-b)^2 = a^2-2ab+b^2
5^2-2*5*6x+(6x)^2
25-60x+36x^2

(5-6x)^2
(5-6x)(5-6x)=
First=5 times 5=25
Outside=5 times -6x=-30x
Inside=-6x times5=-30x
Last=-6x times -6x=36x^2
Put together and combine
36x^2 -60x +25
