Answer:
so the factors of x²+3x-4 are (x-1)(x+4
Step-by-step explanation:
Let x²+3x-4=0
by using sum and product rule
x²+4x-1x-4=0
Taking common
x(x+4)-1(x+4)=0
(x-1)(x+4)=0

Answer:
y=2x+3
Step-by-step explanation:
equation format: y=mx+b
m=slope
b=y-intercept
replace those letters with those things and you can have a perfect linear equation
First term t(1)=(x-y)
common ratio =(x+y) (don't omit the parentheses)
then the nth term:
t(n)=(x-y)(x+y)^(n-1)
check:
t(1)=(x-y)(x+y)^(1-1)=(x-y)(x+y)^0=(x-y)(1)=(x-y)
t(3)=(x-y)(x+y)^(3-1)=(x-y)(x+y)^2
When n is small, t(n) can also be found by repeated multiplication of the common ratio (x+y)
