Is expansion necessary for this quadratic equation?

AI Thread Summary
The equation (x+3)(x-4)(x-2)(x+1) = 24 represents a quartic polynomial, not a quadratic, due to its degree. It is impossible to transform it into a quadratic equation without multiplying the expressions, as the coefficients of x^4 and x^3 cannot be canceled out. The right-hand side of the equation is a constant, further confirming that expansion is necessary. Additionally, the product of the constants in the brackets equals 24, reinforcing the need to expand the equation. Therefore, expansion is essential to analyze the equation properly.

(x+3)(x-4)(x-2)(x+1) = 24
Can we change it into a quadratic equation without multiplying the expressions under those brackets?

No, this will be a quartic (4th degree in x) whichever way you play with it. You can easily see this because the only way for it to become a quadratic is if the LHS x4 and x3 coefficients are cancelled, which isn't going to happen since the RHS only has a constant.

You should realize that 3 times 4 times 2 is equal to 24, so you definitely want to expand.
 
Suppose ,instead of the usual x,y coordinate system with an I basis vector along the x -axis and a corresponding j basis vector along the y-axis we instead have a different pair of basis vectors ,call them e and f along their respective axes. I have seen that this is an important subject in maths My question is what physical applications does such a model apply to? I am asking here because I have devoted quite a lot of time in the past to understanding convectors and the dual...
Insights auto threads is broken atm, so I'm manually creating these for new Insight articles. In Dirac’s Principles of Quantum Mechanics published in 1930 he introduced a “convenient notation” he referred to as a “delta function” which he treated as a continuum analog to the discrete Kronecker delta. The Kronecker delta is simply the indexed components of the identity operator in matrix algebra Source: https://www.physicsforums.com/insights/what-exactly-is-diracs-delta-function/ by...
