Answer:
1. zeros are -2 and 1
2. zeros are -1 and 3
3. zeros are -3 and 1
4. zeros are -1
5. no zeros
6. no zeros
Step-by-step explanation:
Zeros are points on the graph that are x-intercepts; in the graph we can see that they cross -2 and 1 on the 1st equation, -1 and 3 on the 2nd equation, -3 and 1 in the 3rd equation, and -1 in the 4th equation. Since it intersects no x-intercepts in the 5th and 6th equation, it has no zeros.
Answer:
60
Step-by-step explanation:
Answer: The answers are given below.
Step-by-step explanation: We are given to factorise some quadratic expressions.
We will be using the following factorisation formula:

The factorisation is as follows:
We have

Thus, option (B)
is correct.

Thus, option (B)
is correct.

Thus, option (B)
is correct

Thus, option (D)
is correct.

Thus, option (C)
is the correct option.

Thus, option (B)
is the correct option.

Thus, option (D)
is correct.
