What are the zeros of the function?

Answer with explanation:

Zeroes of Function

Zeroes of the Single variable function are those values or those real numbers  which when embed into the Single variable function,it becomes equal to Zero.

Suppose ,a function is ,

f(x)=ax²+bx +c

By Splitting the middle term, and then factorizing,

=a×(x-A)×(x-B)

Put, f(x)=0

→a×(x-A)×(x-B)=0

→x-A=0  ∧ → x-B=0

x=A, ∧ x=B,→are Zeroes of the polynomial or the function.

When you substitute ,these values in the function it will become equal to Zero.

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10
