Answer:
Step-by-step explanation:
A quadratic equation can be factorised if and only if there are rational roots.
For any quadratic equation the discriminant decides about the nature of roots.
Thus only if the discriminant is a perfect square we can have rational roots and in this case only factorization is possible.
In the given equation
Since 1 is a perfect square we can factor and solve
I believe it would be done like this:
subtract 2x-8 from both sides. then use cubric formula.
answer should be x= 1.688242
Answer:83 -->17-->103-->43-->7-->1
Have a good day
Answer:
AB = 8/ cos 60
Step-by-step explanation:
We want to find the hypotenuse AB
Since we have a right triangle
cos theta = adj/ hyp
cos 60 = 8/ AB
AB cos 60 = 8
AB = 8/ cos 60
Answer:
-1/3x + 5
Step-by-step explanation:
The slope-intercept is y = mx + b
The m is the slope and b is the y-intercept.
The equation is:
y = -1/3x + 5
