What is the first step in simplifying the expression 11x-2-3(1-7x)^2+(x+1)?

PEMDAS is a great way to figure this out!

P - Parenthesies

E - Exponents

M - Multiplcation

D - Division

A - Addition

S - Subtraction

Follow this order and you should be good to go! Here's how I would follow this in this equation.

11x-2-3(1-7x)^2+(x+1)

First, parentheses

The 3 directly next to the parenthesies shows that everything inside of the () needs to be multiplied by 3.

-3*1  and -3*-7x (don't forget the negative)

This gives us 11x-2+(-3+21x)^2+(x+1)

Now distribute the exponents to everything inside of the parentheses.

11x-2+-3^2+21x^2+(x+1)

now solve the numbers with exponents without a variable.

3^2 = 3*3 = 9

combine any numbers without a variable outside of parentheses

11x-2+9+21x^2+(x+1)

11x+7+21x^2+(x+1)

From here, what I would do is divide the whole equation by 2

5.5x+3.5+21x+(.5x+.5)

now combine x values outside of parentheses

3.5+26.5x+(.5x+.5)

I believe this would be the simplest form, but please do correct me if I'm wrong or made any errors

there has been genes found in the x chromosome of males that have been linked to [homo/hetero]sexuality. in addition to the reign of the x chromosome, a section of chromosome 8 has also been link to, "alot of ppl are so " these facts were proven true after a 2014 study of a gay male and his strait brother. according to newscientist.com,"chromosome 14 and is mainly active in the thyroid, but also the brain. called tshr, it makes a type of receptor protein that recognises and binds to a hormone that stimulates the thyroid. in this way, the gene plays an important role in controlling thyroid function. the fact that tshr seems to be involved in sexual orientation fits with evidence that thyroid function seems to be linked to sexuality."

in conclusion, "ppl are so gay" due to their genetics.

a = 3.14

b = 18

c = 18/5 or 3.6 or 3 3/5
