A polynomial of degree zero is a constant term

The grouping method of factoring can still be used when only some of the terms share a common factor A True B False

The sum or difference of p and q is the of the x-term in the trinomial

A number a power of a variable or a product of the two is a monomial while a polynomial is the of monomials

What is the LCM of 25 What is the LCM of10 What is the LCM of 75?

"lcm" means least common multiple; usually you would need to calculate the least common multiple of two or more numbers.The least common multiple of a single number is quite trivial: it's the number itself. Thus, the lcm of 25 is 25; etc.

Least Common Multiple of 454 and 463 with GCF Formula The formula of LCM is LCM (a,b) = (a ร— b) / GCF (a,b). We need to calculate greatest common factor 454 and 463, than apply into the LCM equation. GCF (454,463) = 1

What is the LCM of 64and 72?

To calculate the LCM, you first have to split the numbers up into their prime factors: 64 = 2x2x2x2x2x2 72 = 2x2x2x3x3 The next step is to calculate the HCF. In this case it will be 2x2x2 = 8. Finally, you multiply the two numbers and divide by the HCF: 64x72/8 = 576 And therefore the LCM of 64 and 72 is 576.

What is the least common multiple of decimals and fractions in C?

To calculate the least common multiple (lcm) of decimals (integers) and fractions you first need to calculate the greatest common divisor (gcd) of two integers: int gcd (int a, int b) { int c; while (a != 0) { c = a; a = b % a; b = c; } return b; } With this function in place, we can calculate the lcm of two integers: int lcm (int a, int b) { return a / gcd (a, b) * b; } And with this function in place we can calculate the lcm of two fractions (a/b and c/d): int lcm_fraction (int a, int b, int c, int d) { return lcm (a, c) / gcd (b, d); }


What is the LCM of 6 7 8?

The Least Common Multiple (LCM) of (6,7,8) is 168.We can calculate the LCM of three numbers by splitting it up into two LCM calculations. First, we will find the LCM of any two numbers, and then find the LCM of that number, and the last number.To start, let's find the LCM of 6 and 8. The only common factors of 6 and 8 are 1 and 2, so we will multiply those two numbers to get 2, and divide the 6x8 by 2, getting 24.Now we need to find LCM(24, 7). The only common factor of 24 and 7 is 1, so the LCM of 6, 7, and 8 is (24x7)/1=168.
