<u><em>Answer:</em></u>

<u>The zeroes of the equation are:</u>

0, 3, 6 and 7

<u><em>Explanation:</em></u>

<u>Zeroes of an equation</u> are defined as values of x which make the equation equivalent to zero

<u>Remember that</u> in multiplication, if any of the terms is zero, then the product is equal to zero

<u>The given equation is:</u>

x(x-3)(x-6)(x-7) = 0

Now, we will take each term, equate it to zero and find the corresponding x value which makes this term a zero

<u>For the first term:</u>

x = 0 .................> 1st zero

<u>For the second term:</u>

x-3 = 0 .............> x = 3 ................> 2nd zero

<u>For the third term:</u>

x-6 = 0 ............> x = 6 .................> 3rd zero

<u>For the fourth term:</u>

x-7 = 0 ............> x = 7 ...................> 4th zero

Now, from the above, we can conclude that:

The zeroes of the equation are 0, 3, 6 and 7

<u>Another solution:</u>

Zeroes of an equation are represented graphically as the intersection between the function and the x-axis

Therefore, we can graph the function and get the intersection

The graph is attached below and the intersections are shown to be at:

(0,0) , (3,0) , (6,0) and (7,0)

This means that the zeroes are 0, 3, 6 and 7

Hope this helps :)

Is 3/4 bigger than 3/5
Svet_ta [14]
Yes, 3/4 is bigger than 3/5.
One way you can verify this is by drawing a bar model, and cut it into four. Color in three pieces.
Then, draw another bar model the same size as the first one, and cut it into five pieces.
Color in three pieces.
You can see that 3/4 has more shaded in area than 3/5.
Another way you can do this is by dividing the numerator by the denominator for both fractions.
Hope this helped.

What is the factor of x³ 5x² 2x 24?
Delvig [45]

The factors of the expression x³-5x²-2x+24 are: (x+2)(x-3)(x-4)

<h3>What is a factor?</h3>

A factor is a number that completely divides another number.

In other words, since the result may be divided by the two whole numbers we are multiplying, they are factors of the result if multiplying two whole numbers produces a result.

The numbers that can divide a number exactly are called factors.

There is none left over after division as a result.

The numbers you multiply together to produce another number are called factors.

A factor is hence the division of another number.

So, we have the expression: x³-5x²-2x+24

Now, calculate the factors as follows:

x³-5x²-2x+24

We already know that: P(-2) = 0

Hence, x+2 is a factor.

Now, other factors are: x² - 7x + 12

x² + 4x + 3x + 12

(x - 3)(x - 4)

Therefore, the factors of the expression x³-5x²-2x+24 are: (x+2)(x-3)(x-4)
