Answer:
(x-3) (x-5)
Step-by-step explanation:
x²−8x+15
note that the constant term is 15 and the x-coefficient is -8
step 1: List factors of 15 : ±1, ±3, ±5, ±15
step 2: observe the factors listed and ask ourselves the following questions:
1) What 2 factors in the list , when multiplied gives the constant 15
2) What same 2 factors when added gives the x-coefficient -8
by deduction or trial and error, we can see that -3 and -5, when multiplied gives 15 and when added gives -8. Hence these become the factors.
Hence the factors are
(x-3) (x-5)
Infinite they’re all multiples, so they are the same line
Answer:
-7n =12
n=5
Step-by-step explanation:
You said increased so that makes me think you are talking about multiplying so you would write it as -7n =12 :)
If correct, can you please mark me brainliest:)
Option A). 7, -4 and 1/3
To find the zeros you can factor the polynolial into (3x-1)((x+4)(x-7)
Then:
3x -1 =0 => x = 1/3
x+4=0 => x = -4
x-7 =0 => x =7
Those are the three zeros.
