Question

2z^2 - 3 = -5z

Answer 1

come on man, just add 5z to both sides

Answer 2

2z^2+5z-3=0

Answer 3

then
do i factor or use the formula

Answer 4

either or. both will get u the same answer

Answer 5

then how do i factor it

Answer 6

because it's easier

Answer 7

(2x+a)(x+b)
a*b=-3
2b+a=5
solve for a and b

Answer 8

in this case its probably easier to use the quadratic formula,
(-b±√b^2-4ac)/2a = (-5±√25-24)/4 = -5+1 / 4 and -5 - 1 / 4
thus roots are z=-1 and z = -3/2

Answer 9

cool thanks

Answer 10

that makes alot more sense

Answer 11

i actually would have preferred to factor.
(2x-1)(x+3)=2x^2+5x-3
x=1/2 and x=-3
also it should b sqrt(25+24)

Answer 12

what do you mean it should be sqrt does that mean the answer is wrong
