factor it our use quadratic formula (i would do both so you get practicce in both sicne some polynomial are factorable so oyu will have to know how to use wuad formula) this isn't factorable so use quad formula which is -b + or - square root of (b^2 - 4AC) all of that will...
imma teach you how i learn to factor tak the x^2 and multiply it with the 20 giving you 20x^2 now figure out all the numbers that multiply to equal 20 which should be 4 and 4, and 1 and 20 now out of those 2 choices which one adds up to equal 9 (bc there is a 9x) the answer is...
6a +54 all you had to do was multiply everything in parenthesis by the 6 so 6 times a is 6a, and 6 times 9 is 54 giving you the above answer
i got 17.05% you might have put in one of thenumbers wrong check again
its okay i jsut wanted to make sure i had your question right
are you saying everything is like this 0.5x^3 + 0.4^3 - 0.1^3 ? if so just do it like simple adding and subtracting .5+.4 is 0.9x^3 -0.1^3 that becomes 0.8x^3 when adding or subtracting variables with exponent keep all exponent the same
no problem lol this one almost had me stump for alittle
1) rewrite cosx (cosx/sinx) + sinx = csc x 2) cosx^2/sinx + sinx = csc x 3) multiply sinx by (sinx/sinx) to get same denominator this gives you cosx^2/sinx + sinx^2/sinx = cscx 4) combine your fractions (cosx^2 + sinx^2)/sinx = cscx 5) rewrite numerator 1/sinx= csc x and there...
use the quadratic formula(look it up yourself)
