Answer:

  • A) x² - 8x +15

Explanation:


\tt \left(x-3\right)\left(x-5\right)

Apply the FOIL method:-


\boxed{\tt \left(a+b\right)\left(c+d\right)=ac+ad+bc+bd}


\tt x^2 -5x-3x+15

Combine like terms:-


\tt x^2+(-5x-3x)+15

Simplify:-


\tt x^2-8x+15

Therefore, A) x² - 8x +15 is our answer.

Given:-

  • A expression (x-3)(x-5) is given to us .

To find:-

  • To convert the given expression as trinomial .

Answer:-

The given expression to us is ,

(x-3)(x-5)

and we are interested in converting this into trinomial . A trinomial is a expression which has three terms in it. So , we can write the given expression as ,

= x( x-5) - 3(x-5)

= x² - 5x - 3x +15

= - 8x + 15

This is the required trinomial expression.

and we are done!
