Answer:
(4x)^2 = x + 15 or
16x^2 = x + 15
16x^2 - x - 15 = 0
or x =1 and x = -0.9375
Make sure next time that you ask a question..
Step-by-step explanation:
This shouldn't really be answered unless we are sure when the answer is there.
4x is the product of a number and 4
(4x)^2 = 16x^2
this will equal x + 15
16x^2 = x + 15
The question is that the answer? I suspect it is.
16x^2 - x - 15 = 0
This might be the answer. It's not clear.
"""""""""""""""""""""""""""""""""""""''''
Believe it or not, this factors without using the quadratic formula
(16x + 15) ( x - 1) = 0
16x + 15 = 0
x = - 15/16 = - 0.9575
x - 1 = 0
x = 1
