Let p(x) = x3 23x2 + 142x 120 Checking p(x) = 0 So, at x = 1, p(x) = 0 Hence, x 1 is a factor of p(x) Now, p(x) = (x 1) g(x) g(x) = ( ( ))/(( 1)) g(x) is obtained after dividing p(x) by x 1 So, g(x) = x2 22x + 120 So, p(x) = (x 1) g(x) = (x 1) (x2 22x + 120) We factorize g(x) i.e. x2 22x + 120 x2 … Web📌Hi everyone! 😃 Today, we're going to learn how to factorise monic quadratics! 😎Factorising a monic quadratic expression means expressing it as the produc...

Web29 de out. de 2015 · Explanation: The difference of squares identity can be written: a2 −b2 = (a −b)(a +b) In order to treat x2 −5 as a difference of squares, we need to recognise that 5 = (√5)2, then we find: x2 −5 = x2 −(√52) = (x −√5)(x +√5) In other words, we let a = x and b = √5.
