Question

solutions of x squared equals negative 5x +8

Answer 1

Answer:

x = (-5 + 7i)/2 and x = (-5 - 7i)/2

Step-by-step explanation:

x^2 = -(5x+8)

x^2 + 5x + 8 = 0 ----- (i)

by this formula we can find the roots of equation.

x = [-b+√(b^2-4ac)]/2a and x = [-b-√(b^2-4ac)]/2a

hence on comparing the (i) from ax^2+ bx + c = 0

x = [-5+√((5^2)-4×1×8]/2 and x = [-5-√((5^2)-4×1×8]/2

x = (-5 + 7i)/2 and x = (-5 - 7i)/2

i is an imaginary.
