Question

4 root3 a² + 5a - 2 root 3

Answer 1

Answer:

a = √3/4; -2/√3.

Step-by-step explanation:

4√3a² + 5a - 2√3 = 0

4√3 a² + 8a -3a -2√3 = 0

4a (√3a+2) -√3 (√3a+2)

=> (4a-√3)(√3a+2)

4a-√3 = 0 ;       √3a+2 = 0

4a = √3 ;             √3a = -2

a= √3/4;              a = -2/√3

a = √3/4; -2/√3.
