Question

Factorise - 3x² - 7x + 1

Answer 1

Factoring 3x2-7x-1 The first term

Factoring 3x2-7x-1 The first term is, 3x2 its coefficient is 3 .The middle term is, -7x its coefficient is -7 .The last term, "the constant", is -1 Step-1 : Multiply the coefficient of the first term by the constant 3 • -1 = -3 Step-2 : Find two factors of -3 whose sum equals the coefficient of the middle term, which is -7 . -3 + 1 = -2 -1 + 3 = 2
