Answer:
B
Step-by-step explanation:
12x² - 157x - 40
Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term
product = 12 × - 40 = - 480 and sum = - 157
The factors are + 3 and - 160
Use these factors to split the x- term
12x² + 3x - 160x - 40 ( factor the first/second and third/fourth terms
= 3x(4x + 1) - 40(4x + 1) ← factor out (4x + 1) from each term
= (4x + 1)(3x - 40) ← in factored form → B
Queremos tener todos los variables del mismo typo en un lado así que vamos a mover la -x a la izquierda, y el 15 a la derecha.
15 + 3x = 21 - x
+x +x
————————
15 + 4x = 21
-15 -15
———————
4x = 6
— —
4 4
X = 1.5 para ver si es correcto puedes tratar de poner 1.5 en lugar de la x y te saldrá una ecuación correcta :), déjame saber si tienes preguntas espero que eso hizo sentido.
