Answer:

Hi, record yourself or do a video presentation of you explaining what's the answer of x²+2x+1 2x+2 and 2x2+7x+3 2x²–5x-3.

Step-by-step explanation:

base on my calculations, this is the solution and answers, but im not sure hehe.

1.1     Factoring  x2+14x+2 

The first term is,  x2  its coefficient is  1 .

The middle term is,  +14x  its coefficient is  14 .

The last term, "the constant", is  +2 

Step-1 : Multiply the coefficient of the first term by the constant   1 • 2 = 2 

Step-2 : Find two factors of  2  whose sum equals the coefficient of the middle term, which is   14 .

     -2   +   -1   =   -3     -1   +   -2   =   -3     1   +   2   =   3     2   +   1   =   3

Answer: x2 + 14x + 2

Number 2 solution and answer is :

Changes made to your input should not affect the solution:

 (1): "x3"   was replaced by   "x^3".  3 more similar replacement(s).

STEP1:Equation at the end of step 1

((4•(x2))-(5•(x3)))-((2•(x2))-7x3)

STEP 2 :

Equation at the end of step2:

((4•(x2))-(5•(x3)))-(2x2-7x3)

STEP 3 :

Equation at the end of step3:

((4 • (x2)) - 5x3) - (2x2 - 7x3)

STEP 4 :

Equation at the end of step4:

(22x2 - 5x3) - (2x2 - 7x3)

STEP5:

STEP6:Pulling out like terms

 6.1     Pull out like factors :

   2x3 + 2x2  =   2x2 • (x + 1) 

Answer : 2x2 • (x + 1)
