4.2 Solving 9×2-6x+1 = 0 by Completing The Square . This quadratic equation has one solution only.

Answer. Yes it is a perfect square trinomial.

Notice that 9×2 is a perfect square, as (3x)2 = 9×2 and that 16 is a perfect square, as 42 = 16. However, the middle term, –24x is negative, so try 16 = (−4)2. In this case, the middle term is 2(3x)( −4) = −24x. So the trinomial 9×2 – 24x + 16 is a perfect square and factors as (3x – 4)2.

A perfect square is a number that can be expressed as the product of two equal integers. You can tell if a number by finding its square root and seeing if that square root is a whole integer.

A: No, the number 76 is not a perfect square.

The square root of 76 is 2√19 or approximately 8.71780.

77 is not a perfect square.

Since 77 is not a perfect square, it is an irrational number. This means that the answer to “the square root of 77?” will have an infinite number of decimals. The decimals will not terminate and you cannot make it into an exact fraction.

Question 212117: what two integers is 77 squared between? 5928 and 5930 are two integers that 5929 is between.

Yes, there is, both are prime numbers and are not perfect squares. So √29 is an irrational number.

Correct: It is irrational because 77 is not a perfect square. I say: A) Irrational There is a negative symbol, also there is no number. It is neither rational nor irrational; it is a complex or imaginary number.

Yes, any number that can be written as a fraction like that is rational. It’s still rational as the decimal form can be written as both 13/3 or the decimal.

Is Square Root of 99 Rational or Irrational? √99 cannot be written in the form of p/q. Hence, it is an irrational number.
