The answer is a equals 6.
Answer:
49
Step-by-step explanation:
26- (-23)
26 + 23 This is because when you have a negative times a negative it equals a positive.
Answer:
-16
Step-by-step explanation:
x^2 -1 /x+4
By putting the value of x in the expression as x = -7
= (-7)^2 - 1/ -7 +4
= (+49) - 1/ -3
= 48/-3
= -16
Answer:
85
Step-by-step explanation:
got it right
I find the following method easiest to factor this equation.
1. First, fill in what you know would be the factors for the first value, 3x^2. The number 3 only has 2 factors: 3 and 1. Therefore, we know the first values are:
(3x _____)(x_____)
2. Next, figure out what the possible factors for the last value would be (-6). The following combinations are possible:
2 and -3 OR -3 and 2
-2 and 3 OR 3 and -2
-1 and 6 OR 6 and -1
1 and -6 OR -6 and 1
3. Plug in the combinations into step 1 and see which gives you the correct answer:
<span>(3x + 2)(x - 3) = 3x^2 - 7x - 6 --> no
</span>(3x - 3)(x + 2<span>) = 3x^2 + 3x - 6 --> no
</span>(3x - 2)(x + 3) = 3x^2 + <span>7x - 6 --> YES</span>
