Question

8a=34²-26² solve using identities
plz
​

Answer 1

$8a = {34}^{2} - {26}^{2} \\ 8a = 1156 - 676 \\ 8a = 480 \\ a = \frac{480}{8} \\ a = 60$

Answer 2

8a=34^2 - 26^2

8a= (34-26) (34+26)

8a= 8 × 60

8a = 480

a= 480/8

a= 60

hope it's help you...

formula :

${ a}^{2} - {b}^{2} = (a + b) \: (a - b)$
