Is this trinomial a trinomial square x2-18x plus 81?
x2-18x+81 = (x-9)(x-9) when factored
How do you factor out 3x2 plus 54x plus 243?
Divide all terms by 3 and so x2+18x+81= (x+9)(x+9) when factored
What are the factors of the following polynomial k2 plus 18k plus 81?
To factor this, find two numbers whose product is 81 and sum 18. These two numbers are therefore 9 and 9. So we can rewrite the polynomial in its factored form as follows: (k+9)(k+9), or "k plus 9 squared"
What is 78 plus 79 plus 80 plus 80 plus 81 plus 81?
78 + 79 + 80 + 80 + 81 + 81 = 479
What does 30a2 plus 89a plus 63 factored down to?
30a2+89a+63 = (5a+9)(6a+7) when factored
Can 81 plus 16x2 be factored?
There's no root and there's no variable, so no, it can't be factored, but it can be simplified to 113.
Factor the expression 640b plus 648?
It is 8(80b+81) when factored
Is this trinomial a trinomial square x2-18x plus 81?
x2-18x+81 = (x-9)(x-9) when factored
How do you factor out 3x2 plus 54x plus 243?
Divide all terms by 3 and so x2+18x+81= (x+9)(x+9) when factored
What is 9x squared minus 6xy plus y squared minus 81 factored as?
9x2 - 6xy + y2 - 81 = (3x - y)2 - 92 = (3x - y - 9)(3x - y + 9)
What are the factors of the following polynomial k2 plus 18k plus 81?
To factor this, find two numbers whose product is 81 and sum 18. These two numbers are therefore 9 and 9. So we can rewrite the polynomial in its factored form as follows: (k+9)(k+9), or "k plus 9 squared"
What is the factored form of the polynomial x2 plus 9x plus 20?
It is (x+4)(x+5) when factored
What is 78 plus 79 plus 80 plus 80 plus 81 plus 81?
78 + 79 + 80 + 80 + 81 + 81 = 479
What is x2 - 2x plus 1 factored?
It is (x-1)(x-1) when factored
What is 2a plus 2b in factored form?
2(a+b) is 2a plus 2b in factored form.
What does 30a2 plus 89a plus 63 factored down to?
30a2+89a+63 = (5a+9)(6a+7) when factored
