A quadratic equation ax2 + bx + c = 0 has exactly two (possibly repeated) solutions in the complex numbers. We can even write an algebraic expression for them
B(v w) = wT Bv. If the matrix B is singular
For the equation l(a) l(- a) = 0 implies that l(a) 2 = l(a) (l(- 1) + l(-a)) must be equal to l(a) l(- 1). 23 Inventmnes mathVol. 9. Page 3. 320. J. Mdnor
Which equation is a quadratic equation?
x m2= (2x2+ x) m2 So, 2x2+ x= 300 (Given) Therefore, 2x2+ x– 300 = 0 So, the breadth of the hall should satisfy the equation 2x2+ x– 300 = 0 which is a quadratic equation. Many people believe that Babylonians were the first to solve quadratic equations.
How to find the roots of a quadratic equation?
ax2+ bx + c= 0 are given by – ±–42 2 bb ac a This formula for finding the roots of a quadratic equation is known as the quadratic formula. Let us consider some examples for illustrating the use of the quadratic formula. Example 10 : Solve Q. 2(i) of Exercise 4.1 by using the quadratic formula. Solution :Let the breadth of the plot be xmetres.
How to solve q 2(I) of exercise 4.1 using a quadratic formula?
Example 10 : Solve Q. 2(i) of Exercise 4.1 by using the quadratic formula. Solution :Let the breadth of the plot be xmetres. Then the length is (2x+ 1) metres. Then we are given that x(2x+ 1) = 528, i.e., 2x2+ x– 528 = 0. This is of the form ax2+ bx+ c= 0, where a= 2, b= 1, c= – 528. So, the quadratic formula gives us the solution as
Did Babylonians solve quadratic equations?
Many people believe that Babylonians were the first to solve quadratic equations. For instance, they knew how to find two positive numbers with a given positive sum and a given positive product, and this problem is equivalent to solving a quadratic equation of the form x2– px+ q= 0.
