Which equations could be solved using the quadratic formula?
Type your answer here...5x2 - 3x + 10 = 2x2x2 - 6x - 7 = 2x
Is 4x plus 5c plus 10c-3x equals 0a quadratic equation?
NO,because in quadratic equation highest power of a variable is 2. e.x. 4x2-20x+10=0.
Explain a Quadratic equation and how to solve it?
A quadratic equation is any equation that can be expressed as ax2 + bx + c = 0.Note that the a, b and c are specified, x is the only unknown.Example:x2 - 10x - 24 = 0a, b, c are the coefficients of each term.Now x2 appears not to have a coefficient, but remember x2 is the same thing as 1x2 so the coefficient is 1. So a = 1.The second term has a coefficient of -10 because it has a minus, not plus sign in front of it so b = -10.Likewise for c, the third term. C = -24.So you have your terms.There are two popular ways of solving this.You can factorise the equation, or use the Quadratic Formula.I prefer to use the Quadratic Formula, as it is very straightforward, you just need to practise it.The quadratic formula is x = (-b±√(b2-4ac))/2a
What is the answer to x2-2x 10?
Original:i don't think there is an answer. there has to be a number before the x in x2-2x10.by SamanthaActually, there is an answer. It involves using the imaginary number i.To solve:1. Rewrite the equation as x2-2x+10=0.2. This now can be used as a, b, and c for the quadratic formula. (A=1, B=-2, C=10)The quadratic formula is: -b +/- the square root of 4-4(a)(c) ALL divided by 2(a).You then get a negative in the radical which you can convert to an imaginary number using an i.ANOTHER UPDATE:That would be right if she had a mathematic sign before the number 10, but she doesn't. Sorry, man. That's a whooooole different problem.You find that x is something in a+bi form.
What two numbers when multiplied OR added together equal 10?
5+5 By quadratic equation the two numbers (roots) are: 8.872983346 and 1.127016653 Added together = 10 Multiplied = 10
