-x2 + x + 42
= -x2 + 7x - 6x + 42
= 7x - x2 + 42 - 6x
= x(7 - x) + 6(7 - x)
= (7 - x)(x + 6)
No.
In actual fact, the prime factorization of 42 is not 21 x 2, as 21 is not a prime number. The complete prime factorization of 42 is 2 x 3 x 7.
the LCM of 42 and 126 using a prime factorization is 2 times 2 times 3
42=2^3*7
No, prime factorization of 42 is not 21 x 2 because 21 is not a prime number and it can be further broken into primes as 3 x 7. So prime factorization of 42 is 2 x 3 x 7.
(-x-6)(x-7)
42 = 2 × 3 × 7
42 = 2 × 3 × 7
It is: 2*3*7 = 42
No. Prime factorization is the method of expressing a number as the product of prime numbers. So, Prime factorization of 42 = 2x3x7
No.
In actual fact, the prime factorization of 42 is not 21 x 2, as 21 is not a prime number. The complete prime factorization of 42 is 2 x 3 x 7.
42 = 2 × 3 × 7
42 21,2 7,3,2
It i: 2*3*7 = 42
No.
