Question

(x+3) (x+4) answerrrrr

Answer 1

Hey mate,

ATQ,

(x+4)(x+3)

just open the brackets and multiply,

= x^2 + 3x + 4x +12

= x^2 + 7x + 12

hope this helps you out!

Answer 2

Answer:  The answer is $x^2+7x+12.$

Step-by-step explanation:  We are given to evaluate the product of two linear expressions with one unknown variable 'x'.

The given product is

$E=(x+3)(x+4).$

Here, 3 ≠ 4, so we will be using the following formula to get the result.

$(x+a)(x+b)=x^2+(a+b)x+ab.$

Therefore,

$E\\\\=(x+3)(x+4)\\\\=x^2+(3+4)x+3\times 4\\\\=x^2+7x+12.$

Thus,

$(x+3)(x+4)=x^2+7x+12.$
