Question

x²+3x-40 factorise plsans​

Answer 1

As per the details provided in the question.

In the above question, we have the details as follow.

The given data is the given equation x²+3x-40.

We have to find the value of the factorise.

Here we have to simplify the given equation.

Thus, simplifying the equation we get,

$=x^{2} +3x-40$

Now by considering the sum and product rule we get,

$=x^{2} +8x-5x-40\\=x(x+8)-5(x+8)$

solving the factor is,

$=(x-5)(x+8)$

Hence the factorizing the equation we get the factor as $(x-5)(x+8)$.
