Answer:Factoring x4-169x2+3600
The first term is, x4 its coefficient is 1 .
The middle term is, -169x2 its coefficient is -169 .
The last term, "the constant", is +3600
Step-1 : Multiply the coefficient of the first term by the constant 1 • 3600 = 3600
Step-2 : Find two factors of 3600 whose sum equals the coefficient of the middle term, which is -169 .
-3600 + -1 = -3601
-1800 + -2 = -1802
-1200 + -3 = -1203
-900 + -4 = -904
-720 + -5 = -725
-600 + -6 = -606
-450 + -8 = -458
-400 + -9 = -409
-360 + -10 = -370
-300 + -12 = -312
-240 + -15 = -255
-225 + -16 = -241
-200 + -18 = -218
-180 + -20 = -200
-150 + -24 = -174
-144 + -25 = -169 That's it
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -144 and -25
x4 - 144x2 - 25x2 - 3600
Step-4 : Add up the first 2 terms, pulling out like factors :
x2 • (x2-144)
Add up the last 2 terms, pulling out common factors :
25 • (x2-144)
Step-5 : Add up the four terms of step 4 :
(x2-25) • (x2-144)
