Answer:

the trinomial is a perfect square trinomial, there will be some properties to check for.

a

x

2

±

b

+

c

both

a

and

c

must be perfect squares, with plus signs

check whether

b

is the square of a binomial.

It will factorise as:

Answer:

6.5

Step-by-step explanation:

25*2+60x+12

50+60x+12

62+60x

x=62/60

x=31/30

=1.5
