Answer:
The solution to the equation is x = 0.38 or -18.38
Step-by-step explanation:
x^2+18x=7 can be properly written as

To solve by completing the square, divide the coefficient of x by 2, square and then add to both sides
i.e 18/2 = 9
Then add 9² to both sides of the equation

This becomes





∴ 

Hence, x = 0.38 or -18.38
Answer:
x=1.5$x=-3/7
Step-by-step explanation:
(2x-3)(2*2+7x-1)
