Question

how do you simplify 2x^2+3x-3? also, x^2+2x+1?

Answer 1

nevermind let me redo it

Answer 2

how is your teacher solving? using the quadratic equation?

Answer 3

yeah, its part of a "quadratic inequalities" worksheet

Answer 4

but so far, she has just been factoring it not using the quad formula ex: x^2+2x-8=0 so (x+4)(x-2)=0 so x can be -4 or 2

Answer 5

but I guess you could do it both ways

Answer 6

so
2x^2=a
3x=b
-3=c

=\[-3\pm \sqrt{(3)^2-4(2)(-3)}\div(2\times2)\]

Answer 7

yeah but that's rad 33, I think its supposed to be nice #

Answer 8

first you try -3+sqrt(9+24)/4 which is -1.56
and then -3-sqrt(9+24)/4 which is -4.436

so x=-1.56 and -4.436

Answer 9

ok thx
