(x 2 -1) (x+1) therefore, the factorisation of x 3 + x 2 –x – 1 gives (x 2 -1) (x+1) solved examples question 1: check whether x+3 is a factor of x 3 + 3x 2 + 5x +15. solution: let x + 3= 0 => x = -3 now, p(x) = x 3 + 3x 2 + 5x +15 let us...
例如,对于$x^3 + 3x^2 + 3x + 1$,可以将其分组为$(x^3 + 3x^2) + (3x + 1)$,然后利用公式法和提取公因式进行分解。 因式分解在解决数学问题中的应用 因式分解在解决数学问题中具有广泛应用。在代数方程中,通过因式分解可以将方程转化为更简单的形式,便于求解。在不等式证明中,...

Let f(x) = 3x^4 + x^3 + 4x^2 + 4x + 3 be a polynomial in Z_5x. Factorise f(x) as far as possible. Factorise the polynomial f(x) = 2x^3 +15x^2+3x-72 , if we know that f(-3) = 0. Factor the polynomial expression. 48 (4 x - 1)^2 - 75 (2 y + ...
Use the equation 3x² +5x-2 as an example and find the binomial factors. Step 2 Factor the equation 3x² +5x-2 by breaking down the 5x term into the sum of two terms, ax and bx. You choose a and b so that they add up to 5 and when multiplied together give the same product...
