Question

Factorise x^2-32x-165​

Answer 1

Step-by-step explanation:

The first term is, x2 its coefficient is 1 .

The middle term is, -32x its coefficient is -32 .

The last term, "the constant", is -165

Step-1 : Multiply the coefficient of the first term by the constant

$1 \times - 165 = - 165$

Step-2 : Find two factors of -165 whose sum equals the coefficient of the middle term, which is -32 .

No two such factors can be found .
