Factor the trinomial by grouping.<br> 6x^2 - 7x-20
mezya [45]

Answer:

(3x+4)(2x-5)

Step-by-step explanation:

You have 6x^2 - 7x-20, you add and take 8x so now you have

6x^2 - 7x +8x -8x -20 now you take 6x^2  and the +8x and factorize

6x^2 +8x = 2x( 3x +4 )

and you have -7x -8x-20 = -15x -20 factorize

-5(3x +4 ) add all up.

2x(3x +4) -5(3x +4) and you have

(3x+4)(2x-5)

Which number has the prime factorization 5 · 72 · 32?
lubasha [3.4K]

Answer:

see below

Step-by-step explanation:

5*72*32 is not a prime factorization to begin with because neither 72, nor 32 are primes. A prime factorization for this product would be:

2*2*2*2*2*2*2*2*3*3*5

and the number with this factorization is 11520.

There is a small chance that what you meant to write was this: 5\cdot 7^2 \cdot 3^2 in which case the number for this prime factorization is 2205.
