Answer:

3(2x-5)(x+2)

Step-by-step explanation:

Given is an algebraic expression in x in degree 2 as

6x ^2 - 3x - 30

and we have to factor completely.

Seeing the coefficients we find that GCF is 3.

So 3 is a factor

Given expression =

3(2x ^2 - x - 10)\\

Inside product of last term and coefficient of I term is 20.

5x4 =20 and difference = -1 = the middle term

Hence

3(2x ^2 - x - 10)\\=3[2x^2-5x+4x-10]\\=3(2x-5)(x+2)

Paul [167]

Answer:

1

4

9

16

25

36

49

64

81

100

Step-by-step explanation:

1 = 1²

4 = 2 x 2 = 2²

9 = 3 x 3 = 3²

16 = 4 x 4 = 4²

25 = 5 x 5 = 5²

36 = 6 x 6 = 6²

49 = 7 x 7 = 7²

64 = 8 x 8 = 8²

81 = 9 x 9 = 9²

100 = 10 x 10 = 10²

A line passes through (2, 4) and (-2, 2). Find the value of y if (6, y) lies on the line. Not sure how the 3 was brought into th
Marrrta [24]

Answer:

Well, that is simple. You first must find the slope of the line from the 2 given points by using the slope formula. Which is y2-y1/x2-x1. So 2-4/-2-2 which equals -2/-4 which is 1/2. So the slope is 1/2. Now we can use the slope intercept form which is y=mx+b to find the slope equation. So we plug in one the points, say (2,4) and get y=1/2x+3. So now we plug in (6,y) Since we know x we can find y. y=1/2(6)+3 which gives us y=6. So y is 6.
