Question

find the roots of the following equations by applying different methods.,a. 2x square +5x-3=0 b. x2 +5(x+1)=0 c. 2x square +x+3=0​

Answer 1

Step-by-step explanation:

a).2X²+5x-3=0

a=2,b=5,c=-3

we know the formula to find the quadratic equation

x=(-b+-√b²-4ac)/2a

therefore

x=(-5+-√25+24)/4

x=(-5+-7)/4

x=1/2,. x=-3

b). X²+5X+6=0

x=(-5+-√25-24)/12

x=-1/3, x=-1/2

c).2X²+X+3=0

x=-1+-√23/4

x=(-1-√23)4.

x=(-1+√23)4

hope it was helpful plz mark as brainlist the above answer is 100% correct
