(x+1)^2 . (x^2+1) = 0

Maurinko [17]

Answer:

$x^4+2x^3+2x^2+2x+1$

Step-by-step explanation:

Given that,

$(x+1)^2 . (x^2+1) = 0$

We know that, $(a+b)^2=a^2+b^2+2ab$

So,

$(x+1)^2=x^2+1+2x$

So,

$(x+1)^2 . (x^2+1) = (x^2+1+2x)(x^2+1)\\\\=x^2\times x^2+x^2+2x^3+x^2+1+2x\\\\=x^4+2x^3+2x^2+2x+1$

So, the value of the given expression is equal to $x^4+2x^3+2x^2+2x+1$

I need help i can't get the right answer

dimulka [17.4K]

Answer:

x = 50

Step-by-step explanation:

I guess, this diagram tells us that the lines are parallel.

that means that they cut the third line at the exact same angles.

and that means

3x - 26 = 2x + 24

x - 26 = 24

x = 50
