Answer:

Step-by-step explanation:
First of all let's notice that
while our original polynomial is real. So we can rule out the even options B and D. At this point, if the polynomial has a factor of
it means tha
is a zero of the polynomial. Let's check both 2 (for option a) and -2 (for option c)


At this point 2 is a zero, and our final factoring is a
Answer:
x = 7
Step-by-step explanation:
Expand 3x+2(x-5)=25 which looks like
3x+2x-10=25
Add similar elements: ( 3x+2x = 5x)
5x-10=25
Add 10 to both sides
5x-10+10 = 25 + 10
Simplfy
5x = 35
Divide both sides by 5
5x ÷ 5 = 35 ÷ 5
Simplfy:
x = 7
have a wonderful day
Answer:
The first one: 19/15a
second one: b²-4ac = D
Step-by-step explanation:
for first one: take LCM and solve
for second one: you square the expression on both sides then b²= D + 4ac, then when you take 4ac to the left hand side, it becomes b²-4ac= D
