So what you need to do is to put X alone so what you do is +3 on both sides so only 7x=7x is left. then do the opposite and divide 7 with 7 you get 1x thats your answer
Answer:
4x^2+17x+15
Step-by-step explanation:
(4x-3)(x+5)
= 4x(x+5) -3(x+5)
= 4x^2+ 20x -3x + 15
= 4x^2 + 17x + 15
Step-by-step explanation:
i think this is the answer if its wrong im sorry
Answer:
See below.
Step-by-step explanation:
It would take a long time to explain . There is a good method called Newton's method which involves graphs of the type
y = x^3 - n and applying calculus to produce cycles of approximation until you'll get close to the required cubic root.
You'll find it on online videos.
