Factorise 3(x+y)^2-5(x+y)+2-Namely, the parenthetical factor x – y This binomial may be different from what I'm used to seeing referred to as being a "factor", but the factorization process works just the same for this expression as it did for every other17 Factorisation (EMAG) Factorisation is the opposite process of expanding brackets For example, expanding brackets would require \(2(x 1)\) to be written as \(2x 2\)

You need factors of 2 that multiply to 2 but added give 5 (which is the middle term) You can, however, solve for x using the quadratic formula if you set the equation equal to zero 3x^2 5x 2 = 0 Quadratic formula x = (b / (square root)b^2–4ac)/2a a = 3 b = 5 c = 2 x = (5 / (square root)25–4*3*2)/2*37/22/12 · y= x^3 3x^2 2 First we need to calculate the critical values of y, to do so, we need to find the first derivative's zeros Let us differentiate y' = 3x^2 6x 3x^2 6x = 0 Factor 3x4/11/16 · The factors are (xy)(xy) or (xy)^2 We need to factor the trinomial x^22xyy^2 The factors of x^2 = (x)(x) The factors of y^2 = (y)(y) Since the second sign is positive we are adding the factors meaning the signs of the factors need to be the same Since the first sign is negative both signs must be negative
