Question

solve by factoring 2a^2 - 3a = -5

Answer 1

2a^2-3a=-5
2a^2-3a+5=0
a^2-3a+10=0
(a+2)(a-5)=0
a+2=0
a=-2
a-5=0
a=5

5 and -2

Answer 2

(a+2)(a-5)=0
=> a=5,-2

Answer 3

2a2 -3a +5 not is equal (a+2)(a-5) so i think that this not is right,correct sure !!!

Answer 4

2a2 -3a+5=0
a1,2=(3+/- sqrt(9-40))/4 =(3+/- isqrt31)/4

Answer 5
