Use the quadratic formula to find the zeros of the function. Round to tenths if necessary. y = 17x2 - 21
So since its not in ax^2 + bx + c wouldnt it be no real solution?
A. {-1.1, 1.1}
B. {1.1}
C. {-4.1, 4.6}
D. no real solution

Question

anonymous · Answer

why isn't it $$ax^2 + bx + c$$

? 

b is simply zero...

anonymous · Answer

oh i seeee wow my dad told me otherwise :P

anonymous · Answer

although it should say $$0 = 17 x^2 - 21$$

(the zero _is_ important) 
hope that was just a typo on your side?

Got the result yet?

haha

anonymous · Answer

the answer is A - not B... (cause you cant tell if a number was positive or negative after squaring it... hence the +/- in front of the sqrt in your formula...)
