5 - 8x + 3x2

= 3x2 - 8x + 5 (since the sign of the second term is negative, then 5 can be factored as (-1)(-5))

= (3x - )(x - ) (try to put 1 or 5 to the empty places, in order to obtain -8x)

= (3x - 5)(x - 1)

I need help with factor?

If you mean factor pairs then I know: Factor pairs and factors are both same things and for example this is a factor pair: 4x5, 6x5, 7x5. Factors or factor pairs is an equation that equals to a total: for example: factors of 20: 5x4, 4x5. BONUS: If one number has 2 or more factor pairs then that is a composite. If a number only has below and 2 that is a prime number.
