2k^2 + 9k = -7 using quadratic equation
Pepsi [2]

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)
