Answer:
- Trinomials in the form
can often be factored as the product of two binomials.
Step-by-step explanation:
As we know that a polynomial with three terms is said to be a trinomial.
Considering the trinomial of a form
![ax^2+bx+c](https://tex.z-dn.net/?f=ax%5E2%2Bbx%2Bc)
As
a = 1
so
![x^2+bx+c](https://tex.z-dn.net/?f=x%5E2%2Bbx%2Bc)
- Trinomials in the form
can often be factored as the product of two binomials.
For example,
![x^2+7x+10](https://tex.z-dn.net/?f=x%5E2%2B7x%2B10)
![=\left(x^2+2x\right)+\left(5x+10\right)](https://tex.z-dn.net/?f=%3D%5Cleft%28x%5E2%2B2x%5Cright%29%2B%5Cleft%285x%2B10%5Cright%29)
![=x\left(x+2\right)+5\left(x+2\right)](https://tex.z-dn.net/?f=%3Dx%5Cleft%28x%2B2%5Cright%29%2B5%5Cleft%28x%2B2%5Cright%29)
![\mathrm{Factor\:out\:common\:term\:}x+2](https://tex.z-dn.net/?f=%5Cmathrm%7BFactor%5C%3Aout%5C%3Acommon%5C%3Aterm%5C%3A%7Dx%2B2)
![=\left(x+2\right)\left(x+5\right)](https://tex.z-dn.net/?f=%3D%5Cleft%28x%2B2%5Cright%29%5Cleft%28x%2B5%5Cright%29)
Therefore, Trinomials in the form
can often be factored as the product of two binomials.
