Answer: (x+4)(x+5)
Step-by-step explanation:
x²+9x+20=(x+4)(x+5)
Answer:
x=1+/-4i
Step-by-step explanation:
(x+1)/3-(2x-1)/x=-1
find the common denominator,
in this case, it's going to be 3x.
(x^2+x)/3x-(6x-3)/3x=-1
(x^2+x-6x+3)/3x=-1
x^2-5x+3=-3x
x^2-5x-(-3x)+3=0
x^2-5x+3x+3=0
x^2-2x+3=0
apply the quadratic formula in order to find the roots for x.
Since ax^2+bx+c=0, in this case,
a=1, b=-2, c=3
--------------------------
x=(-b+/-sqrt(b^2-4ac))/2a
x=(2+/-sqrt(4-12))/2
x=(2+/-8i)/2
x=1+/-4i
Answer: The answer here is x=2
Step-by-step explanation:
This is a linear equation, take 5x to other side ut will change a sign then solve for x.
2x+5=21
2x=21-5
2x=16
Lastly divide by 2 both sides to get 2
