Factorise 2x² + 4 12x+3 3
Answers
Answer:
Step-by-step explanation:
Factoring 2x2+412x+33
The first term is, 2x2 its coefficient is 2 .
The middle term is, +412x its coefficient is 412.
The last term, "the constant", is +33
Step-1 : Multiply the coefficient of the first term by the constant 2 • 33 = 66
Step-2 : Find two factors of 66 whose sum equals the coefficient of the middle term, which is 412 .
-66 + -1 = -67
-33 + -2 = -35
-22 + -3 = -25
-11 + -6 = -17
-6 + -11 = -17
-3 + -22 = -25
-2 + -33 = -35
-1 + -66 = -67
1 + 66 = 67
2 + 33 = 35
3 + 22 = 25
6 + 11 = 17
11 + 6 = 17
22 + 3 = 25
33 + 2 = 35
66 + 1 = 67
