Equate x-1 with 0 i.e., x – 1 = 0 which gives us x = 1Now if we substitute the value of x in p(x) we get,p(1) = 4(1)^3 + 3(1)^2 – 4(1) -3 = 4 + 3 – 4 -3 = 0 Thus, we can conclude that x – 1 is a factor of the given expression (as the remainder is equal to 0)We can even factorise a polynomial equation ax2 + bx + c by splitting the middle term as ax^2 + bx + c = (px + q) (rx + s) = pr x^2 + (ps + qr)x + asSo, by comparing the coefficients of x^2, we get a = orSimilarly, comparing the coefficients of x, we get b = ps + qrand, c = qs.
