Answer:
Step-by-step explanation:
Factoring x2-6x-30
The first term is, x2 its coefficient is 1 .
The middle term is, -6x its coefficient is -6 .
The last term, "the constant", is -30
Step-1 : Multiply the coefficient of the first term by the constant 1 • -30 = -30
Step-2 : Find two factors of -30 whose sum equals the coefficient of the middle term, which is -6 .
-30 + 1 = -29
-15 + 2 = -13
-10 + 3 = -7
-6 + 5 = -1
-5 + 6 = 1
-3 + 10 = 7
-2 + 15 = 13
-1 + 30 = 29
Answer: 57/20, or 2.85, or 2/ 17/20
Step-by-step explanation: These are all the same anwsers but in deffrent form
Answer:
<h2>only x = 39</h2>
Step-by-step explanation:
x + 6 = 45 <em>subtract 6 from both sides</em>
x + 6 - 6 = 45 - 6
x = 39
