Question

For what value of k, 7 is zero of polynomial
2x+9x + 3K-1 ? Also find the other zero of polynomial​

Answer 1

Answer:

k= -25

Step-by-step explanation:

2x+9x+3k =1

given that

7 is zero of the polynomial

then

x = 7

2(7)+9(7)+3k =1

14 + 63 +3k = 1

77 + 3k = 1

3k = 1-77

3k = -76

k = -76/3

k = -25.3333....

k= - 25.34

let us assume

k = -25

thank you.....
