Question

factories the following 6x4-23x2+20​

Answer 1

Answer:

Step-by-step explanation:

Solve the given equation .

On substituting in the given equation we get,

Now to factorize the equation first we will factorize the trinomial . Since the constant term of the trinomial (which is 20) is positive and the coefficient of x term (which is –23) is negative so the constant terms of the both factors will have negative sign.

The factors of the first term 6u2 are u, 6u or 2u, 3u and the factors of the constant term 20 (both negative) are –2, –10 or –1, –20 or –4, –5.

Now we notice that for the trial factors the middle term of the product is which is same as the middle term of the trinomial . So these trial factors are the required factors and we have,

So we can factorize the equation as shown below,
