Answer:
first choice is the correct answer
Answer:
The last choice.
Step-by-step explanation:
The last term is - 20 and because we have a coefficient of 1 on the x^3, and in order to get this last term and the given roots the factors have to be
(x + 5)(x + 4)(x - 1) so it is the last option.
4x² - 3xy + 9y² - 3(5xy + 7y²)
4x² - 3xy + 9y² - 3(5xy) - 3(7y²)
4x² - 3xy + 9y² - 15xy - 21y²
4x² - 3xy - 15xy + 9y² - 21y²
4x² - 18xy - 12y²
(10+×)^2
expand
(10+x)(10+x)
multiply
100+10x+10x+x^2
add
100+20x+x^2
rearrange
x^2+20x+100
if this is what you mean this is the answer if you want to know what x is just set ()=0 and solve
x+10=0
x=-10
but I believe you are asking for the equation hope that helps let me know :)
We want to make their denominators the same to add them, their common denominator is 16
So 5/8 will become 10/16
now we can add both fractions easily
10/16 + 1/16 = 11/16
