X^2 + 5x - 24 = 0 How do I solve by factoring

Mathematics
1 answer:
tiny-mole [99]3 years ago
7 0

Answer:

x = -8 or x = 3

Step-by-step explanation:

To factor ax² + bx + c, use AC method.

a times c is 1 × -24 = -24.

Factors of ac (-24) that add up to b (5) are 8 and -3.

Divide by a and reduce: 8/1 and -3/1.

Therefore, the factors are x + 8 and x − 3.

x² + 5x − 24 = 0

(x + 8) (x − 3) = 0

x = -8 or 3

Find g(x)-f(x). g(x)=x^2+1 and f(x)=2x+5
UkoKoshka [18]

Answer:

g(x) - f(x) = x^{2} - 2x - 4

Step-by-step explanation:

g(x) - f(x) = (x^{2} + 1) - (2x + 5)

<em><u>Multiply the -1 in then add the two expressions together.</u></em>

(x^{2} + 1) + (-2x - 5) = x^{2} - 2x - 4

1. un numar se mareste cu 4 iar rezultatul se mareste de 4 ori. noul rezultat micsorat cu 4 se imparte la 4 si se obtine 4.aflat
Marat540 [252]

Răspuns:

1

Explicație pas cu pas:

Fie numărul = x

x + 4 = e - - (1)

e * 4 = f - - - (2)

Ecuația 2 - 4 împărțită la 4 = 4

(f - 4) / 4 = 4

Crucea se înmulțește

f - 4 = 16

f = 16 + 4

f = 20

Rezultatul 1 împărțit la 4 este egal cu 4

Prin urmare,

e = f / 4

f = 20

e = 20/4

e = 5

De la (1)

x + 4 = e

x + 4 = 5

x = 5 - 4

x = 1

How can you determine the domain and range of function.
Mice21 [21]

Answer:

The domain of a function is the complete set of possible values of the independent variable.

In plain English, this definition means:

The domain is the set of all possible x-values which will make the function "work", and will output real y-values.

When finding the domain, remember:

The denominator (bottom) of a fraction cannot be zero

The number under a square root sign must be positive in this section

Step-by-step explanation:
