Question

Which shows the unsimplified solution for 2x2 + 7x – 5 = 0?

Answer 1

i am not sure but i think your answer is 1/7

Answer 2

use quadratic formula
for
ax^2+bx+c=0
x=
`(-b+/- √(b^2-4ac) )/(2a)`
a=2
b=7
c=-5

the unsimplified solutions are

x=
`(-7+ √(7^2-4(1)(-5)) )/(2(1))` and
`(-7- √(7^2-4(1)(-5)) )/(2(1))`
