Trinominal!  Fancy work for something so simple.

And @Jimmy, perhaps you can explain how you got that.

anonymous · Answer

yes please explain cuz i dont understan

anonymous · Answer

ok - i should have explained

anonymous · Answer

these trinomials which  can be factored give two parenthesis with two terms in each.

there will be x in each bracket  (to make the x^2) and the two numbers are found as follows

in this case you need two numbers which when multiplied together give +30 and when added/ subtracted make -11.
these are -5 and -6

we can check if we are right by expanding

(x-5)(x-6) = x(x-6) - 5(x-6) = x^2 - 6x - 5x + 30 = x^2 -11x + 30

are you ok with that?

anonymous · Answer

they are a bit tricky and need some practice before you are confident with them
