ax2 + bx + c = 0 , find the value of x . b2-4ac>o x is real (2 different values will solve) b2-4ac=o -> a double root (a single real number will solve it) x=real numbers. b2-4ac<0 x= two complex number roots (either pure imaginary or a complex number with real and imaginary components)
x + y = 28 x*y = 7 x=7/y replacing X in eq 1 7/y+y=28 y^2 - 28y + 7 = 0 using above solutions find the reciprocal and sum -- Dhruv
The answer to the question is given in the question!If you want to find the value of an algebraic expression, then you need to substitute numerical values for each of the variables in the expression, and then calculate and simplify the result.
Negatives cause no problem: log10x = -3 means x = 10-3 = 0.001 It doesn't make sense, though, to FIND the logarithm of a negative number: log10(-8) = ???? (unless you know about complex numbers . . . )
You muliply the base times the height of one of the triangles in the trianagular prism (both triangles will be similar, proportional, and equal, and you divide that number by two or multiply that number by 1/2, then you multiply that number times the height or length of one triangle's end to the other triangle's end of the triangular prism to obtain your final volume. The formula is as follows. V=1/2(b*h)(height)
The reciprocal of a number plus the reciprocal of twice the number equals Find the number. 1/2 find the number
Number x Reciprocal = 1 Therefore Reciprocal = 1/Number
The reciprocal is the inverse of a number, or n-1. To find a reciprocal, change the number to a fraction and invert the numerator and the denominator.
The reciprocal of a number is what the original number is multiplied by to get 1. To find this you can simply divide 1 by the number you want the reciprocal for or, if the number is in fraction form, switch the denominator and numerator.
To find the reciprocal of a number, calculate  [divided by] [the number].
To find the reciprocal of any number, divide ' 1 ' by the number. 1 / (0.8) = 1.25
To find the reciprocal of a whole number, you must first write it as a fraction. You do this by writing x/1, if the number is 4, it would be 4/1. Then you would find the reciprocal of that fraction. So using the same example, the reciprocal of 4 is 1/4.
