Answer: $x-2$

Step-by-step explanation:

The quadratic equation given in the problem above can be solve by factoring it.

You must find two numbers whose sum is -9 and whose product is 14. These number would be: -2 and -7

Therefore, keeping this on mind you have:

$(x-2)(x-7)=0$

Therefore, a factor of the given quadratic equation is $x-2$

Can someone please help with this math question:)

Bingel [31]

Solution:

The rationalisation factor for $\frac{1}{ a - \sqrt{b} }$ is $a + \sqrt{b}$

So, let us apply it here.

$\frac{1}{5 - \sqrt{2} }$

The rationalising factor for 5 - √2 is 5 + √2.

Therefore, multiplying and dividing by 5 + √2, we have

$= \frac{1}{5 - \sqrt{2} } \times \frac{5 + \sqrt{2} }{5 + \sqrt{2} } \\ = \frac{5 + \sqrt{2} }{(5 - \sqrt{2})(5 + \sqrt{2} ) } \\ = \frac{5 + \sqrt{2} }{ {(5)}^{2} - ( \sqrt{2})^{2} } \\ = \frac{5 + \sqrt{2} }{25 - 2} \\ = \frac{5 + \sqrt{2} }{23}$

Answer:

$\frac{5 + \sqrt{2} }{23}$

Hope you could understand.

If you have any query, feel free to ask.

Step-by-step explanation:

First of all their is an easier way solving this 2l/ + l^2

but how you need it is c because the base is 100 and each face is 40 how 10x8=80 80/2=40
