Question

find product
(x+7)(x2 + 3x +5)
​

Answer 1

Answer:

x3+10x2+26x+35

Step-by-step explanation:

=(x+7)(x2+3x+5)

=(x)(x2) + (x)(3x) + (x)(5) + (7)(x2) + (7)(3x) + (7)(5)

=x3+3x2+5x+7x2+21x+35

=x3+10x2+26x+35

Answer 2

As per data given in the question,

We have to find the product when (x+7) is multiplied to $(x^2+3x+5)$

So, for multiplying we have to multiply the individual number of first set to the individual number of second set.

So, we will get,

$(x+7) (x^2+3x+5)\\x\times (x^2)+x\times 3x +5\times x +7x^2+21x+35\\x^3+3x^2+5x+7x^2+21x+35\\x^3+10x^2+26x+35$

Hence, the answer will be $x^3+10x^2+26x+35$
