Answer:
I wouldn't even say that the answer is 0.
Step-by-step explanation:
I say that because you can not simplify -x.
33 rounds to 30 and 89 rounds to 80. 80 x 30= 2400
Quadratic equation: ax² + bx + c =0
x' = [-b+√(b²-4ac)]/2a and x" = [-b-√(b²-4ac)]/2a
6 = x² – 10x ; x² - 10x -6 =0
(a=1, b= - 10 and c = - 6
x' = [10+√(10²+4(1)(-6)]/2(1) and x" = [10-√(10²+4(1)(-6)]/2(1)
x' =5+√31 and x' = 5-√31
