Answer:
x=-8 x=2
Step-by-step explanation:
x^2 +6x-6 = 10
Subtract 10 from each side
x^2 +6x-6-10 = 10-10
x^2 +6x-16 = 0
Factor
What 2 numbers multiply to -16 and add to +6
8*-2 = 16
8-2 =6
(x+8) (x-2) =0
Using the zero product property
x+8 = 0 x-2 =0
x=-8 x=2
Answer:

Answer:
7
Step-by-step explanation:
Criteria:
• same number of books on each shelf
⇒find a number that divides 58 and 145
• greatest number of books on each shelf
⇒find the greatest number that divides 58 and 145
Find the GCF of 58 and 145.
58 = 2 ⋅ 29
145 = 5 ⋅ 29The GCF of 58 and 145 is 29.
Each shelf will contain 29 books.
There are 203 total books (because 58 + 145 = 203).
Divide 203 by 29 to find the number of shelves there should be.
203 / 29 = 7
Therefore, there will be 7 shelves.
The answer would be(-4,8)...i think☺
The zeros of m(x) =x^2-4x+3 are 1 and 3
