Maya is showing her work in simplifying (5.2 − 4.5) − 5.5 + 4.8. Identify any error in her work or reasoning.

1 answer:

7 0

If putting 5.2 and 4.5 in fraction form, her error must have been timing 3 by 3 to 5.2 and 4.5 as a fraction. Meaning that 5.5 and 4.8 is wrong

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