Answer:

(1,0)

(-2,3)

(5,24)

Step-by-step explanation:

To solve this you can can just plug in the x and y values and see which work

y = x²-1

Lets test (0,1):

1 = 0²-1

1 = -1

This pair <em>does not</em> work, because 1 does not equal -1

Lets test (1,0):

0 = 1²-1

0 = 0

This <em>does</em> work, because 0 equals 0

Lets test (3,5):

5 = 3²-1

5 = 9 - 1

5 = 8

This pair <em>does not</em> work, because 5 does not equal 8

Lets test (5,24):

24 = 5²-1

24 = 25 -1

24 = 24

This pair <em>does</em> work, because 24 equals 24

Lets test (-2,3):

3 = (-2)²-1

3 = 4-1

3 = 3

This pair <em>does</em> work, because 3 equals 3

Lets test (-4,-17):

-17 = (-4)²-1

-17 = 16 - 1

-17 = 15

This pair <em>does not</em> work, because -17 does not equal 15

So the pairs that are on the graph are:

(1,0)

(-2,3)

(5,24)

<h2>Answer:</h2>

I hope it will helps u

<h2>Step-by-step explanation:</h2>

As given

x²-3x-10

Now according to the one of the rule of factorization ,

we have to find such two values whose product becomes equal to the

"product of first and last term " and if we sum those numbers it should be equal to the "middle term of it".

so such numbers are   -5x and +2x

if we add or multiply them we get the above

as  adding    -5x+2x=-3x  (middle term)

also multiplying   -5x*2x=-10x²  (product of 1st and last term)

so now , we can write as,

x²-3x-10

=x²-5x+2x-10

now making groups of 2 terms,

=(x²-5x)+(2x-10)

now common

=x(x-5)+2(x-5)

now common(x-5)

=(x-5)(x+2)   This is the required factors.....
