I can't really help you with the math but I can give you the formulas for the answers.
A little bit of trained eyeballing can help here. Let me tell you how I saw the answer without any computation.
Remember that the expansion of a squared binomial is
So, the square of a binomial has the following properties, which you can easily spot:
- It has three terms
- Two of them are perfect squares
- The third is twice the product of the two roots.
Well, in this case we do have three terms, and indeed is the square of 11x, and 1 is the square of itself. The only thing we have to check is that 22x is twice the product of 11x and 1, which is true.
So, the answer is
If you want to see some explicit calculations, just use the quadratic formula
to see that there is a double solution , and then use the formula
to come to the same conclusion.
Answer:
x = -2,3
Step-by-step explanation:
Given: (x − 3)(x +2) = 0
To find the solution of above factor.
It is already in factor form.
Two factors are (x-3) and (x+2)
So, set each factor to 0 and solve for x
(x − 3) = 0 or (x +2) = 0
x - 3 = 0 or x + 2 = 0
x = 3 or x = -2
Hence, The solution of the (x − 3)(x +2) = 0 are 3 and -2
It is given that the triangles ITH and APG are congruent.
When the two triangles are congruent, then the corresponding angles and sides are congruent to each other.
By being congruent, the corresponding angles which are congruent are:
Therefore,
SO, Option 2 is the correct answer.
False . x=4
6-2x=24
+2
6x=24
24/6=4
