Bill and jenna are solving the quadratic equation x^2 0 x = 12.
bill solved this way
x^2 0 x = 12
x(x 0 1) = 12
x = 12 or 13
jenna solved this way
x^2 0 x = 12
x^2 0 x 0 12 = 0
(x 0 4)(x + 3) = 0
x = 4 or x = 03
which student is correct?
what error did the other student make when solving?

Jenna is correct. Bill made mistake in his first step, he did not write the equation in general form of quadratic equation.

Step-by-step explanation:

The given equation is

The general form of a quadratic equation is

The given equation can be written as

Therefore, Jenna is correct.

Bill made mistake in his first step, he did not write the equation in general form of quadratic equation.

i understand 100% 10/10 hit or miss?

step-by-step explanation:

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.
