Answer:
An expression will be said to be a perfect square trinomial if it takes the form of ax² + bx + c and if it satisfies the condition b² = 4ac.
Step-by-step explanation:
An expression which is obtained from the square of a binomial equation is known as perfect square trinomial.
Now, the conditions for which an equation will be called a perfect square trinomial are;
i) It is of the form: ax² + bx + c
I) It satisfies the condition: b² = 4ac.
Thus, the perfect square formula could take the following forms:
(ax)² + 2abx + b² = (ax + b)²
Or
(ax)² − 2abx + b² = (ax − b)²
Answer:
The probability of spinning an even number is 1:2, or 50 percent. The probability of rolling an odd number is also 1:2, or 50 percent.
Explanation:
On most number spinners, there are an equal number of odds and evens. This is the same for a dice, since the numbers range from 1-6; 3 odd numbers and 3 even numbers.
