Multiply each side by -5 add 25 to each side
Step-by-step explanation:
- 1/5 (x - 25) = 7
Multiply each side by -5
(x - 25) = -35
add 25 to each side
x-25+25=-35+25
x=-10

2x^2+16x=-18
dividing through by 2 we get:
x^2+8x=-9
but
c=(-b/2a)^2
c=(-8/2)=16
hence
x^2+8x+16=-9+16
x^2+8x+16=7
(x+4)(x+4)=7
(x+4)^2=7
thus getting the square root of both sides
x+4=+/-√7
x=-4+/-√7
x=
