X^2 - 14 x = 15
(x - 7)^2 - 49 = 15
(x-7)^2 = 64
x - 7 = - or + 8
x = 15 or -1
Just take half o the coefficient of x and subtract it squared as above.
In general
x^2 + ax = b
(x + a/2)^2 - a^2/4 = b
Answer:
l=a/w
Step-by-step explanation:
In order to find I you would need to isolate it. In order to do this, you divide both sides by w and end up with a/w=l.
