Question

Use the quadratic formula to find the solutions for..
y = 2x^2 - 9x + 5.

Answer 1

Answer:
`x=(9)/(4)-(√(41) )/(4) \\x=(9)/(4)+(√(41) )/(4)`

Explanation:

`2x^2-9x+5`

a=2

b=-9

c=5

`x=\frac{-b\frac{+}{}√(b^2-4ac) }{2a}`

`x=\frac{-(-9)\frac{+}{}√((-9)^2-4(2)(5)) }{2(2)}`

`x=\frac{9\frac{+}{}√(81-40) }{4}`

`x=\frac{9\frac{+}{}√(41) }{4}`

`x=(9)/(4)-(√(41) )/(4) \\x=(9)/(4)+(√(41) )/(4)`
