Replace * with a number in such a way that the trinomial could be written in the form a(x+b)^2 or a(x-b)^2. a) 1.5x^2+6x+*

b) 2x^2-5x+*

Step-by-step explanation:

a)

b)

Solution given;

a. 1.5x^2+6x+*

1.5(x²+4x+*)

1.5(x²+2.2x+2²)

1.5(x+2)²

b) 2x^2-5x+*

2(x²-5x/2+*)

2(x²-2×5/4 ×x +(5/4)²)

2(x-5/4)²

-22

times both sides by 2, times () by 8, add alile terms, move terms, add alike and caculate divide both sides by 3
