Answer:
C
Step-by-step explanation:
2.88*2.2=6.336, which is approximately 6.34.
He made a mistake in step #2. It seemed to be a trivial mistake because it involved signs, but it still had a great impact. Since step#2, his solution was already wrong.
Instead of
(-1)²-4(2)(-6) = 1 + 48 = 49
What he did is
(-1)²-4(2)(-6) = -1 + 48 = 47
(3*j)-8
I thinkkkk... I’m positive tho
