What is the value of x in ax2 bx c0?
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)
The sum of two numbers is 28 and their product is 7 find the sum of the reciprocals of the numbers?
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
How do you find the value of an algebraic expression by substituting a number for each variable and simplifying?
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.
How do you solve logarithms with a negative in front?
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 . . . )
How do you find volume of triangular prism?
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)

What is reciprocal of a 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.
How do you find the reciprocal?
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.
How do you work out the reciprocal on a calculator?
To find the reciprocal of a number, calculate [1] [divided by] [the number].

How do you find the reciprocal of a whole number?
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.
