Anyone know how to solve this ? ? i need

x = - 7, x = - 4

Step-by-step explanation:

To factor the quadratic

Consider the factors of the constant term ( + 28) which sum to give the coefficient of the x- term ( + 11)

The factors are + 7 and + 4, since

7 × 4 = 28 and 7 + 4 = 11, hence

(x + 7)(x + 4) = 0

Equate each factor to zero and solve for x

x + 7 = 0 ⇒ x = - 7

x + 4 = 0 ⇒ x = - 4

answer: bea's uncle is 25 years old.

step-by-step explanation:

given the equation , we can say that the variable "x" represents the age of bea's uncle. then to find his age, we need to solve for "x":

we must add 15 to both sides of the equation:

now we need to divide both sides of the equation by 3:

therefore, we can conclude that bea's uncle is 25 years old.
