Question

Verify that x =1/2 is a solution of the equation 3 -x –10x^2 = 0. Find the other solution​

Answer 1

Answer:

x=(-3/5)

Step-by-step explanation:

3 -x –10x^2 = 0------------------------->(1)

to verify we put x =1/2 in the equation (1)

3 -(1/2) –10*(1/2)^2

=(5/2)-10*(1/4)

=(5/2)-(5/2)

=0

so ,x =1/2 is a solution of the equation 3 -x –10x^2 = 0.

let, a be the another solution.

then,

3 -x –10x^2 = 0

or, -3 +x +10x^2 = 0

0r, 10x^2+(6-5) x-3=0

or, 5x(2x-1) +3(2x-1)=0

or, (x-1/2)(5x+3)=0

(5x+3)=0

x=(-3/5)

(-3/5) is the other solution.
