Question

Evaluate by using suitable identity:(z + 3/4) (z + 4/3)​

Answer 1

Answer:

Step-by-step explanation:

z ^2 + 4/3 z + 3/4 z + 1

is the answer

Answer 2

Step-by-step explanation:

Identity used--->

-------------------------

(x+a)(x+b)=x^2+(a+b)x+ab

now

(z+3/4) (z+4/3)

= z^2+(3/4+4/3)z+3/4×4/3

= z^2 +(9+16/12)z +1

= z^2 +( 25/12 )z +1
