Factorise this
Answer only if you know ​

Answer 1

Answer:

The first term is, 3x2 its coefficient is 3 .

The middle term is, -12x its coefficient is -12 .

The last term, "the constant", is -10

Step-1 : Multiply the coefficient of the first term by the constant 3 • -10 = -30

Step-2 : Find two factors of -30 whose sum equals the coefficient of the middle term, which is -12 .
