Answer: (2x+5)(2x−5)
Step-by-step explanation:For me, what i like to do is to try divide the problem into two parts. For example in this problem, you would divide the 4x^2 into two 4x(since 4x+4x = 4x^2). Then 25 can be divide into into 5s (5x5=25). SInce you know that its a negative 25, you know that it has to be a negative on one of the sides. So the answer in factor form is (2x+5)(2x−5)

+ 6 +
= 18
First, simplify
to
/ Your problem should look like:
+ 6 +
= 18
Second, simplify
to
/ Your problem should look like:
+ 6 +
= 18
Third, simplify
+ 6 +
to
+ 6 / Your problem should look like:
+ 6 = 18
Fourth, regroup terms. / Your problem should look like: 6 -
= 18
Fifth, multiply both sides by 7. / Your problem should look like: 42 - x = 126
Sixth, subtract 42 from both sides. / Your problem should look like: -x = 126 - 42
Seventh, simplify 126 - 42 to 84. / Your problem should look like: -x = 84
Eighth, multiply both sides by -1. / Your problem should look like: x = -84
Answer:
x = -84
