Ginny factored 6x2 – 31x – 30 as shown: ac = –180 and b = 31 36(–5) = –180 and 36 + (–5) = 31 6x2 + 36x – 5x – 30 6x(x + 6) – 5(
meriva

Answer:

Ginny made a mistake in step 1 when she identified b = 31. It should be b=-31

Step-by-step explanation:

Ginny factored 6x^2 -31x -30 as shown:

ac = –180 and

b = 31

36(–5) = –180 and 36 + (–5) = 31

6x^2 + 36x – 5x – 30

6x(x + 6) – 5(x + 6)

(x + 6)(6x – 5)

b is the coefficient of x and from the trinomial 6x^2 -31x -30, b=-31.

Therefore Ginny made a mistake in step 1 when she identified b = 31. It should be b = –31.

The correct steps are: 6x^2 -31x -30:

ac = –180 and

b = -31

36(–5) = –180 and -36+5 = -31

6x^2-36x +5x -30  

6x(x-6)+5(x-6)

(x-6)(6x+5)
