Which expression is equivalent to x^4 - 2x^3 + x^2?

Mathematics

Answer:

x²(x - 1)²

Step-by-step explanation

Given the expression x^4 - 2x^3 + x^2

Factoring out the common terms;

x^2 (x^2-2x + 1)

Factorize the expression in bracket

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

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

= x^2 (x(x-1)-1(x-1))

= x^2 (x-1)(x-1)

<em>= x^2(x-1)^2</em>

<em>Hence the factored form of the expression is x²(x - 1)²</em>

Answer to the first problem is 3 3/9

Reasoning:

To do these equations, you must change the mixed numbers into just fractions. I will do the first problem :)

2 divided by 3 2/3.

The first step in solving this equation is changing 3 2/3 back into a fraction.

To do this, do the denominator (3) times the whole number (also 3) and then add the numerator (2). 3 x 3 = 9. 9 is now your numerator and 3 is your denominator. 9/3

After this you want to put 10/1 MULTIPLIED by 3/9 (when dividing fractions you must flip the second fraction AND THEN MULTIPLY)

So 10/1 MULTIPLIED by 3/9 = 30/9

It then wants us to simply our answer. To do this, divide 30/9 by 9. You’ll get 3 3/9 as your answer for question 1!

Here is a pic to look at if you need anymore help!

If the average grade on an English class rose from 70 to 85 what is the approximate percent increase ?
mixer [17]

Answer: The approximate percent increase is 121.42857%. This is a rounded value. To get this, first you would need to find out which increased and in what direction. Of course, the 70 turned into an 85. So you can divide 85 by 70 and receive a number. Then in whatever form you found it, decimal, fraction, or even percent straight away, ensure the value is a percentage.

70 -> 85

85/70

About 1.21 [decimal]

1.21 x 100 = 121 [add the %]

121% [rounded]

Factor completely x3 + 4x2 + 8x + 32. (x + 4)(x2 + 8) (x − 4)(x2 − 8) (x − 4)(x2 + 8) (x + 4)(x2 − 8)

\tt x^3+4x^2+8x+32\\\\=x^2(x+4)+8(x+4)\\\\=\boxed{\tt(x+4)(x^2+8)}
