Mathematics

Anna71 [15]3 years ago
6 0

This number has a certain amount of hundreds, tens and ones. We know that there are 8 hundreds, so the number is like 8xy

Also, the tens are 2 fewer than the hundreds, so 2 fewer than 8, which is 6. The number is like 86y

The ones are also 2 fewer than the hundreds, so 2 fewer than 8, which is 6. So, the number is 866.

Why is (x-3) NOT a factor of x3+2x2-5x-6
ivolga24 [154]

As the expression is not equal to zero on x=3, x-3 is not a factor of given expression

Step-by-step explanation:

Given expression is:

x^3+2x^2-5x-6

We have to check if x-3 is a factor of given expression

In order for x-3 to be a factor of expression, we have to put x-3 = 0 => x=3 in expression.

If the expression is zero at x=3 then x-3 is a factor of expression otherwise not.

So putting x=333 in expression

=(3)^3+2(3)^2-5(3)-6\\= 27+2(9) - 15-6\\= 27+18-15-6\\= 45-21\\=24 \neq 0

As the expression is not equal to zero on x=3, x-3 is not a factor of given expression
