Step-by-step explanation:
Here we will, Provide index power 5 on both the sides, so that we can cancel out the 5th power root in the L.H.S
so we get as,
==> x+7 = (-2)^5
==> x+7 = -32
==> x = -32-7
==> x = -39
hence, x = -39
Option A.) is correct.

Step-by-step explanation:
Answer:(k+1)(2K+7)
Step-by-step explanation:
Using the quadratic formula
X=-b±-√b^2-4ac/2a
ax^2+bx+c=0
2k^2+9k+7=0
In this case a=2,b=9,c=7
-9+-√9^2-4(2)(7)/2(2)
(-9+√25)/4=-9+5/4=-1
(-9-√25)/4=-14/4 =-7/2
X=-1,X=-7/2
So (K+1)(k+7/2)
So (k+1)(2k+7)
