Well if there is no number I front of a variable it is a one. For example 12c-c: 12c-1c so just take the numbers and then subtract th m and bring the c down next to the answer. 12-1:11 so 12c-1c:11c

Answer:
x = 3/2, x = -5
Step-by-step explanation:
2x² + 7x - 15 = 0
You're going to factor first using whichever method you prefer, but it's best to always start with GCF over any other method. In this case, this equation does not have one so we'll go with the Lie method and grouping method.
A quadratic is formulated to look like this:
ax² + bx + c = 0
So to start factoring, we're going to multiply "a" and "c" to get -30.
Then, we are going to look at factors of -30 that will add up to "b" and in this case, 10 and -3 multiply to get -30 but also add up 7 so we plug those two numbers in.
2x² + 10x - 3x - 15 = 0
Now, we are going to group them like so:
(2x² + 10x)(-3x - 15) = 0
Finally, we can begin to break it down and find x.
2x(x+5) - 3(x+5) = 0
You're doing this right, if the information in the parentheses match.
(x+5)(2x-3) = 0
Set both (x+5) and (2x-3) to zero and solve.
x = 3/2 and x = -5
Answer:
there is no solution
Step-by-step explanation:
plbecause there is no sso
For problem 1, the number classification problem,
Natural: 1
Whole: 0
Integer: -3
Rational: 6
Irrational: pi
When plotting pi, put it just in front of the number 3
