Simplify (2sqrt(5)+3sqrt(7))^2
~~~
Can you show the steps. I want to learn how to do it now so I won't have to pester y'all again with my feeble algebra questions :3
Using this formula (a+b)^2=a^2+2ab+b^2
we get
(2sqrt(5))^2 + 2(2sqrt(5))(3sqrt(7))+ (3sqrt(7))^2
4(5)+(2*2*3)(sqrt(5)*sqrt(7))+9(7)
20+12sqrt(35)+63
83+12sqrt(35)
thank you... Math gives me a lowkey head ache
Dam why the hell is math so hard when am I gonna use this in real life?
Duuuuude you saved me!! Thanks sooo much! I finally got it now! *fistbump*
When are you gonna use that in real life? forget that! if the teachers do one subject how do they expect a student to master them all? DO I LOOK LIKE AN ANIME PROTAGANIST!?
Finally i found a right response. For some reason i always end up with 153.9907(1539907/10000) and not 153.9929 (83 + 12√35). But the above response was right. Major oof
I really need to finish this quick! Can anyone give me a hand?!
I'm sorry, I didn't mean to pressure. . .
