8 0

2x2−9x−5=02x2-9x-5=0Factor by grouping.
(x−5)(2x+1)=0(x-5)(2x+1)=0Set x−5x-5 equal to 00 and solve for xx.
x=5x=5Set 2x+12x+1 equal to 00 and solve for xx.
x=−12x=-12The solution is the result of x−5=0x-5=0 and 2x+1=02x+1=0.x=5,−12

Factor the expression using the GCF. 60 – 36 =

Ivanshal [37]

Answer

12 (5 - 3)

Step-by-step explanation:

The greatest common factor is the largest number that will divide both numbers evenly. As an example, 6 is a common factor because it divides both 60 and 36. However, it is not the greatest common factor.

If I break 60 into it's prime factors, I would get 2 * 2 * 3 * 5.

If I break 36 into it's prime factors, I would get 2 * 2 * 3 * 3.

The two number have the factors, 2, 2, and 3 in common.

The greatest common factor is then: 2 * 2 * 3, or 12.

The expression can be factored as: 12 ( 5 - 3)
