Question

Multiply and rewrite as a trinomi Please help fast

Answer 1

• 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.

Answer 2

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

= x² - 8x + 15

This is the required trinomial expression.

and we are done!
