Question

(x+6)(x−5)−x2 plizzz

Answer 1

Ответ:

х (во второй степени) - х - 30

Answer 2

To simplify the expression, let's expand and simplify each term:

First, expand (x+6)(x-5):

(x+6)(x-5) = x(x) + x(-5) + 6(x) + 6(-5) = x^2 - 5x + 6x - 30 = x^2 + x - 30

Now, let's simplify the entire expression by substituting the expanded form:

(x+6)(x-5) - x^2 = (x^2 + x - 30) - x^2 = x^2 + x - 30 - x^2 = (x^2 - x^2) + x - 30 = 0x + x - 30 = x - 30

Therefore, the simplified form of (x+6)(x-5) - x^2 is x - 30.
