First you put (x+5) into the initial function wherever you see x so it becomes
(x+5)^2+3(x+5)-10=x^2+kx+30
(x^2+5x+25)+(3x+15)-10 simplified left side
x^2+8x+30 fully simplified left side
thus k=8
x^2+8x+30=0 to find 0s
-4 + 3.7416573867739i
<span>-4 - 3.7416573867739i
</span>these are the roots you find after using the quadratic formula
the second one is the smallest
N equals to 2 so 4 plus 2 is 6 and that is the answer!!
Glad I could help. Have A Good day
7x-3 = 18
+3 for both sides
7x = 21
devide 7 for both sides
x = 3
