A perfect square trinomial is
(square of one term) + (square of another term) + (double the product of the two terms)
Let's look at the following trinomial.
X² - 14x + 49
(x - 7) (x - 7)
(x - 7)²
This trinomial would be classified as a perfect square trinomial because it factors as two identical binomials which is (x - 7)². This means that any trinomial that factors as two identical binomials is called a perfect square trinomial.
Perfect square trinomials are quadratic expressions that can be factored into the square of a binomial, such as a 2 + 2 ab + b 2 or a 2 − 2 ab + b 2 . Examples include x 2 + 6 x + 9 and x 2 − 10 x + 25 . These trinomials can be identified by checking their first and last terms, as well as the middle term.

Jawab:Penjelasan dengan langkah-langkah:The expression "11-7-3-4-12-8-4-x" can be simplified by combining the numerical values. 11 - 7 = 4. 4 - 3 = 1. 1 - 4 = -3. -3 - 12 = -15. -15 - 8 = -23. -23 - 4 = -27. Therefore, the expression simplifies to -27 - x. The question asks "berapa x", which translates to "how much is x". Since the expression is -27 - x, and the question is asking for the value of x, the answer is that x is multiplied by -1.The expression simplifies to: 11 - 7 - 3 - 4 - 12 - 8 - 4 - x = -27 - x.Therefore, the answer is -27 - x.
