Question

Find the value of k if (x+3) is a factor of 3r? + ke +6.​

Answer 1

$\huge{\underline{\mathtt{\red{❥A}\pink{N}\green{S}\blue{W}\purple{E}\orange{R}}}}$

p(X)=p(-3)

therefore X=-3

x+3=0 ( you told me)

let put the Value of X=-3

X²+kx-2 = -3×-3+k×-3-2

9-3k-2

7-3k

-7=-3k

7=3k

k=7/3

Answer 2

p(X)=p(-3)

therefore X=-3

x+3=0 ( you told me)

let put the Value of X=-3

X²+kx-2 = -3×-3+k×-3-2

9-3k-2

7-3k

-7=-3k

7=3k

k=7/3
