Answer: 2535
Step-by-step explanation:
use order of operations (parenthesis, exponents, multiplication/division, addition/subtraction)
first ill handle the two innermost parenthesis
(4 + 3(2 - 8))
(4 + 3(-6))
(4 - 18)
-14
now lets move on to the next parenthesis
( 3 - 5^2(-14))
(3 - 25( - 14)
( 3 + 350)
353
now onto the last part of the problem
8^2 + 7 (353)
64 + 2471
2535 :))
Step-by-step explanation:
5x^2 - 20x + 20 = 5x^2 - 20x + 20
5(x^2 - 4x + 4) = 5(x^2 - 4x + 4)
(5 + 5) (x^2 - 4x + 4)
