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)
