Question

Find the product of (3x + 4)(x − 1). 3x2 + 7x − 4 3x2 + 7x − 3 3x2 − x − 4 3x2 + x − 4

Answer 1

Hello !

Answer:

`\boxed{\sf (3x + 4)(x - 1)=3x^2+x-4}`

Explanation:

We will have to use the distributive property to expand this expression.

Let's remember :

`\sf (a+b)(c+d)=ab+ad+bc+bd)`

Let's apply this property to our expression :

`\sf (3x + 4)(x -1)\\=3x* x+3x*(-1)+4* x+4*(-1)`

Now let's calculate and combine like terms :

`\sf 3x^2-3x+4x-4\\\boxed{\sf =3x^2+x-4}`

Have a nice day ;)
