Factor the four-term polynomial. ab ac - 4b - 4c

The factored form of  the given polynomials ab + ac - 4b - 4c is (b+c)(a-4)      

Step-by-step explanation:

 Consider the given polynomials ab + ac - 4b - 4c

We have to factor the given terms,

Since, there are four term , we can factorize using grouping like terms toether,

Like terms are term having atleast one common factor.

Here, ab and ac are like terms and -4b and - 4c

So, (ab+ ab) + (-4b -4c)

Taking a common from first bracket and -4 common from last two brackets, we have,

= a(b+c) -4(b+c)

Again taking (b+c) common from both, we get,

= (b+c)(a-4)

Thus, The factored form of  the given polynomials ab + ac - 4b - 4c is (b+c)(a-4)

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.
