Question

one root of the quadratic equation
$(2x - 3)(x + 5) = 0$
is-s. then the other rood is​

Answer 1

Step-by-step explanation:

2 roots :

Alpha = -5 , Beta

(2x-3) (x+5) = 0

2x²+10x-3x-15 = 0

2x²+7x-15 = 0

Therefore, a = 2, b = 7, c = -15

We know that,

Alpha * Beta = c/a

-5 * Beta = -15/2

Beta = -15/2*-5

Beta = -15/-10 i.e Beta = 15/10

Therefore, Beta = 1.5 or 3/2

i hope it's helpful for you

Answer 2

Answer:

one root of the quadratic equation

(2x-3)(x+5)=0

is -5

the other root is

2x-3=0

=> 2x=3

=> x=3/2

the other root is 3/2
