Step 
<u>Find the factors of each number</u>
we know that
Step 
<u>Find the greatest common factor (GCF)</u>
the GCF is equal to----------> 
therefore
<u>the answer is</u>
The GCF is 
a)
there are total 3 diffrent shades
because
(i) A = C = 1/2 so one shade
(ii) B=D =F = 2/3 so one shade
(iii) E = 5/8 one shade
so total 3 different shade
b )
(i) y = 1/2 b
(ii) y = (2/3) b
(iii) y = 5/8 b
15 x 15 = 175, that is how to find the square root.
Answer:
An expression will be said to be a perfect square trinomial if it takes the form of ax² + bx + c and if it satisfies the condition b² = 4ac.
Step-by-step explanation:
An expression which is obtained from the square of a binomial equation is known as perfect square trinomial.
Now, the conditions for which an equation will be called a perfect square trinomial are;
i) It is of the form: ax² + bx + c
I) It satisfies the condition: b² = 4ac.
Thus, the perfect square formula could take the following forms:
(ax)² + 2abx + b² = (ax + b)²
Or
(ax)² − 2abx + b² = (ax − b)²
