Using perfect factors find the square root of 1764
Zolol [24]

The square root of 1764 using perfect factors is 42

<h3>How to determine the square root using perfect factors?</h3>

The number is given as:

1764

Rewrite as

x^2 = 1764

Express 1764 as the product of its factors

x^2 = 2 * 2 * 3 * 3  * 7 * 7

Express as squares

x^2 = 2^2 * 3^2 * 7^2

Take the square root of both sides

x = 2 * 3 * 7

Evaluate the product

x = 42

Hence, the square root of 1764 using perfect factors is 42

If x+1 and x-1 are the factors of the polynomial ax^3 + x^2 - 2x +b,find the values of a and b
Nadusha1986 [10]

The polynomial remainder theorem says that dividing a polynomial p(x) by x-c leaves a remainder of p(c)=0 if x-c is a factor of p(x). In this case, check c=-1 and c=1.

a(-1)^3+(-1)^2-2(-1)+b=-a+b+3=0

a(1)^3+(1)^2-2(1)+b=a+b-1=0

From the first equation,

-a+b+3=0\implies a=b+3

and substituting into the second gives

(b+3)+b-1=0\implies2b+2=0\implies b=-1\implies a=2
