Hey plz me out i need all workings

a)x^2-4xy-12y^2 b)x^2+8x+12

see explanation

Step-by-step explanation:

(a)

Consider the factors of the coefficient of the y² term ( - 12) which sum to give the coefficient of the xy- term (- 4)

The factors are - 6 and + 2

since - 6 × 2 = - 12 and - 6 + 2 = - 4, hence

x² - 4xy - 12y² = (x - 6y)(x + 2y)

(b)

Consider the factors of + 12 which sum to give + 8

The factors are + 2 and + 6, hence

x² + 8x + 12 = (x + 2)(x + 6)

the answer is 175.4379

step-by-step explanation:

we'll this would mean that the dunk tank and the bounce house are the same for 20 hours because the 2 represents that the two activities, and the 20 represents the amount of hours they both are. so with this said, it means that the answer is c. the costs for a dunk tank and bounce house are the same for 20 hours.

c.the costs for a dunk tank and bounce house are the same for 20 hours.

hope this .
