Answer:

Brainleist plz

Step-by-step explanation:

Distance from,

There = 50

and Back = 50

speed is...

There = 25+5

Back = 25-5

50/25+5 = 50/30 = 5/3

50/25-5 = 50/20 = 5/2

5/3+5/2 = Total Time spent to go from pier a to pier b and back

Total Time = 25/6 Hours

Harry is trying to solve the equation y = 2x2 − x − 6 using the quadratic formula. He has made an error in one of the steps belo

professor190 [17]

Answer:

Step 2

Step-by-step explanation:

The quadratic formula is given by $x=-b+-\frac{\sqrt{b^{2}-4ac } }{2a}$

Our equation is y = 2x²-x-6

So here our a = 2, b = -1, and c = -6

We can now plug these numbers into our formula

$x= -(-1) +-\frac{\sqrt{(-1)^{2}-4(2)(-6) } }{2(2)} = 1 +-\frac{\sqrt{1+24} }{4} = 1+-\frac{\sqrt{25} }{4}$

Step 2 is incorrect because it states that "x equals the negative of negative 1 plus or minus the square root of negative one plus forty-eight all over two times 2."

The correct statement would be "x equals the negative of negative 1 plus or minus the square root of positive one plus forty-eight all over two times 2.", because the square of a negative is positive, resulting in a positive one.

Since this step is incorrect, the steps after are also incorrect, but Harry went wrong at Step 2
