tekilochka [14]

Answer:

2x^2(3x^2-2x-1)

Step-by-step explanation:

12x^4 - 8x^3 - 4x^2

everything is a multiple of 4 so divide the whole thing by 4

12x^4 - 8x^3 - 4x^2/4= 3x^4-2x^3-1x^2

write it in disturbed form

2(3x^4-2x^3-1x^2)

now if u see we can see that the X will be same, so we also have to factor it out and 2 is the exponent that all can give

2x^2(3x^2-2x-1)

Svetradugi [14.3K]

Answer:

19 wrong answers.

Step-by-step explanation:

Given:

Sahil got 28 questions right.

Angelina got 7 more wrong answers than Sahil.

There where 40 questions on the test.

Question asked:

How many answers did Angelina get wrong on the math test ?

Solution:

Total questions on the test = 40

Number of right answers, Sahil got = 28

Number of wrong answers, Sahil got = 40 - 28 = 12

As Angelina got 7 more wrong answers than Sahil,

Number of wrong answers, Sahil got = 12

Then, number of wrong answers, Angelina got = 12 + 7 = 19

Therefore, 19 answers did Angelina get wrong on the math test out of 40.
