ok this is kinda stupid but i totally just confused myself with the simplest thing haha
okay when doing the FOIL methed to this equation
(-7-y)(-7-y)
would it be 49 + 7y + 7y + y^2
or no??
yes
now collect the like terms to get
y^2 + 14y + 49
haha okayy thankss
No, you are close but not exactly correct. When using the FOIL method to multiply the expressions (-7-y)(-7-y), you need to multiply each term in the first expression with each term in the second expression. Let's break it down step by step:
F: Multiply the first terms: -7 * -7 = 49.
O: Multiply the outer terms: -7 * -y = 7y.
I: Multiply the inner terms: -y * -7 = 7y.
L: Multiply the last terms: -y * -y = y^2.
Now, simplify the expression by combining like terms: 49 + 7y + 7y + y^2.
Combining the middle terms, you get: 49 + 14y + y^2.
So, the correct answer is 49 + 14y + y^2.
