Question

Consider this expression -4x^2+2x-5(1+x)

Answer 1

Answer:

x= (3+√-71)/-8

x= (3-√71)/-8

Step-by-step explanation:

we are given an equation i.e.,

-4x²+2x-5(1+x)

we will solve this,

-4x²+2x-5-5x=0

-4x²-3x-5=0

we will find the value of x:

x= (-b+√b²-4ac)÷2a

x= (3+√9-4×-4×5)÷-8

x= (3+√-71)/-8

Now, x= (-b-√b²-4ac)÷2a

x=(3-√9-80)÷-8

x=(3-√-71)/-80

Hence, we got two roots of x i.e., x= (3+√-71)/-8 and x= (3-√-71)/-8.
