Question

Раскрой скобки: (x+12)⋅(x−4)

Answer 1

(х + 12) • (х - 4)

х² - 4х + 12х - 48

х² + 8х - 48.

Answer 2

To expand the expression (x + 12) ⋅ (x - 4), you can use the distributive property (FOIL method):

FOIL method: First: Multiply the first terms in each set of parentheses: x * x = x^2 Outer: Multiply the outer terms: x * -4 = -4x Inner: Multiply the inner terms: 12 * x = 12x Last: Multiply the last terms in each set of parentheses: 12 * -4 = -48

Now, combine the results:

(x + 12) ⋅ (x - 4) = x^2 - 4x + 12x - 48

Finally, simplify the expression:

(x + 12) ⋅ (x - 4) = x^2 + 8x - 48
