Question

$\frac{5a^{2} +6}{3} = 2a+2$

Answer 1

$\frac{5a^2+6}{3} =2a+2$

$5a^2+6} =3(2a+2)$

$5a^2+6} =6a+6$

$5a^2 =6a+6-6$

$5a^2 =6a$

$5a.a =6a$

$5a =6$

$a = \frac{6}{5}$

Answer 2

5a²  +  6  = 2a + 2
     3

mmc: 3

5a² + 6   =  3 (2a + 2) 
   3                3

5a² + 6  = 6a + 6
5a² - 6a + 6 - 6 = 0
5a² - 6a = 0
a(5a - 6) = 0

a = 0
ou

5a - 6 = 0
5a = 6
a = 6/5
