Question

some one help me plllzzz
factor by grouping;leading coefficient >1
20m^3+28^2+49

Answer 1

Is it 28m not 28?

Answer 2

yhhh right 28m^2

Answer 3

20*49 = 980
factors of 980 = 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490
choose any 2 at reverse end pairs (2,490),(4,196),(ect)
total of 4,196 = 200.
Split 200 into 2 parts based on total.
coeficient a = (28/200)*4
coeficient b = (28/200)*196

20x^2 + 0.56x + 27.44x + 49

I'm not sure if you can directly factor this...
