Is square root of 162 a perfect square?
The number 162 is not a perfect square. The square root of 162 is an irrational number.
What is the square of 163?
The square root of 163 with one digit decimal accuracy is 12.7.
What can divide 169?
The list of all positive divisors (i.e., the list of all integers that divide 169) is as follows: 1, 13, 169. For 169 to be a prime number, it would have been required that 169 has only two divisors, i.e., itself and 1.
How do you factor perfect squares?
FOIL stands for multiply the first, outside, inside, and last terms together. When you FOIL a binomial times itself, the product is called a perfect square. For example, (a + b)2 gives you the perfect-square trinomial a2 + 2ab + b2.
What is the discriminant formula?
The discriminant is the part of the quadratic formula underneath the square root symbol: b²-4ac. The discriminant tells us whether there are two solutions, one solution, or no solutions.
Why is getting the discriminant important?
The quadratic equation discriminant is important because it tells us the number and type of solutions. This information is helpful because it serves as a double check when solving quadratic equations by any of the four methods (factoring, completing the square, using square roots, and using the quadratic formula).
What is the Radicand of a square root?
Lesson Summary The radicand is the number found inside a radical symbol, and it’s the number you want to find the root of. It could be a square root, cube root or other root, which will be defined by the subscript found outside and just before the radical symbol.
When b2 4ac is equal to zero then the roots are?
1. If b2 – 4ac = 0 then the roots will be x = −b±02a = −b−02a, −b+02a = −b2a, −b2a. Clearly, −b2a is a real number because b and a are real. Thus, the roots of the equation ax2 + bx + c = 0 are real and equal if b2 – 4ac = 0.
How do you determine the nature of a root?
To determine the nature of roots of quadratic equations (in the form ax^2 + bx +c=0) , we need to caclulate the discriminant, which is b^2 – 4 a c. When discriminant is greater than zero, the roots are unequal and real. When discriminant is equal to zero, the roots are equal and real.
