Sagot :

Answer:

1. (m + 7)²

2. (2x + 1)²

3. (3x + 5)²

4. (5x - y)²

5. (2a - 9)²

Step-by-step explanation:

solution for every PST(Perfect Square Trinomial):

find the square root of the first term and also last term

ex.: √m² = m

√49 = 7

then look at the second term of trinomial. copy its sign (wether positive or negative)

ex.: + 14m

sign: positive (+)

then place the square root of the first term, the sign and the square root of the last term respectively.

ex.: (m + 7)

m = 1st term

+ = sign

7 = last term
