I would say the answer is either c or a, can’t see the video so i can’t really determine
Do parentheses first according to PEMDAS.
3 squared is 9 and add 4 to get 13
Do 52 minus 13 to get 39
Answer:
Nothing new about leading coefficient. Definition says it can't be zero. It can always be made equal to one by dividing through.
Constant term cannot be zero unless a root is zero.
Step-by-step explanation:
x-3/4 = 0 has root 3/4 constant term -3/4
(x-3/4)(x-b) = 0 has roots 3/4 and b, constant term 3b/4 which is zero only if b is zero.
(x-3/4)(x-b)(x-c) = 0 has roots 3/4, b, c, constant term -3bc/4 which is zero only if b or c is zero.
Etc. ...
it is 10...,,,,....,,,,,,,,,,?,,?????
Angles on a straight line add up to 180°, so:
x + 60 = 180
x = 180 - 60
x = 120°
