Question

Solve by using the quadratic formula

Answer 1

Quadratic Formula

x = -b +- sqrt{b^2 - 4ac}/(2a)

For question H, subtract 4 from 10 and equate to 0. We now let a = 5, b = -7 and c = 6.

Plug into the formula and do the math..

For question I, subtract 7 from 13 and equate to 0. We know let a = 6, b = 2 and c = 6.

Plug into the formula and do the math.

Answer 2

H =

`x = (7 + - i √(71) )/(10)`

I =

`x = ( - 1 + - i √(35) )/(6)`
