What is the factor of k2 + k - 42

marin [14]

Answer:

(k + 7) • (k - 6)

Step-by-step explanation:

Final result :

(k + 7) • (k - 6)

Reformatting the input :

Changes made to your input should not affect the solution:

(1): "k2" was replaced by "k^2".

Step by step solution :

Step 1 :

Trying to factor by splitting the middle term

1.1 Factoring k2+k-42

The first term is, k2 its coefficient is 1 .

The middle term is, +k its coefficient is 1 .

The last term, "the constant", is -42

Step-1 : Multiply the coefficient of the first term by the constant 1 • -42 = -42

Step-2 : Find two factors of -42 whose sum equals the coefficient of the middle term, which is 1 .

-42 + 1 = -41

-21 + 2 = -19

-14 + 3 = -11

-7 + 6 = -1

-6 + 7 = 1 That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -6 and 7

k2 - 6k + 7k - 42

Step-4 : Add up the first 2 terms, pulling out like factors :

k • (k-6)

Add up the last 2 terms, pulling out common factors :

7 • (k-6)

Step-5 : Add up the four terms of step 4 :

(k+7) • (k-6)

Which is the desired factorization

Final result :

(k + 7) • (k - 6)

HELP!!

Liono4ka [1.6K]

Answer:

Part 1: The polygon ABCDE reflected across y-axis to get the polygon MNOPQ. So, the polygon ABCDE congruent to polygon MNOPQ.

Part 2: The vertices of polygon VWXYZ are V(1, 3), W(-1, 7), X(-7, 7), Y(-5, 3), and Z(-3, 1).

Step-by-step explanation:

Part 1:

The vertices of the polygon ABCDE are A(2, 8), B(4, 12), C(10, 12), D(8, 8), and E(6, 6).

The vertices of the polygon MNOPQ are M(-2, 8), N(-4, 12), O(-10, 12), P(-8, 8), and Q(-6, 6).

We need to find the transformation or sequence of transformations that can be performed on polygon ABCDE to show that it is congruent to polygon MNOPQ.

The relation between the vertices of ABCDE and MNOPQ are defined as

$(x,y)\rightarrow (-x,y)$

It means the polygon ABCDE reflected across y-axis to get the polygon MNOPQ. So, the polygon ABCDE congruent to polygon MNOPQ.

Part 2:

If polygon MNOPQ is translated 3 units right and 5 units down, then

$(x,y)\rightarrow (x+3,y-5)$

$M(-2,8)\rightarrow V(-2+3,8-5)=V(1,3)$

$N(-4,12)\rightarrow W(-4+3,12-5)=W(-1,7)$

$O(-10,12)\rightarrow X(-10+3,12-5)=X(-7,7)$

$P(-8,8)\rightarrow Y(-8+3,8-5)=Y(-5,3)$

$Q(-6,6)\rightarrow Z(-6+3,6-5)=Z(-3,1)$

Therefore the vertices of polygon VWXYZ are V(1, 3), W(-1, 7), X(-7, 7), Y(-5, 3), and Z(-3, 1).
