Answer:
x = -2
Step-by-step explanation:
To solve, we need to <u>isolate "x"</u> by moving other numbers to the right side of the equal sign. To "move" a number, <u>do the reverse operation to both sides of the equation</u>. <u>Move numbers in reverse BEDMAS order</u>.
4(-2x - 1) = 12 Do the opposite of times 4
Divide both sides by 4
-2x - 1 = 3 Do the opposite of subtract 1
Add 1 to both sides
-2x = 4 Do the opposite of times -2
Divide both sides by -2
x = -2 Solved for "x"

Answer:
3/2
Step-by-step explanation:
Factor 25 out of 25a^2−100.
Factor 25 out of 25a^2.
25(a^2)−100
Factor 25 out of −100.
25a^2+25⋅−4
Factor 25 out of 25a^2+25⋅−4.
25(a^2−4)
Rewrite 4 as 2^2.
25(a^2−2^2)
Factor.
Since both terms are perfect squares, factor using the difference of squares formula, a^2−b^2=(a+b)(a−b) where a=a and b=2.
25((a+2)(a−2))
Remove unnecessary parentheses.
25(a+2)(a−2)
I believe this is correct.
