Hi i'm really struggling with this and if someone could show the answers and how to do it that would be amazing! It's due tomorrow.

Oh so just use quadratic formula
It’s a lot to solve, but after u will that formula it will be easier
But in second
A=7x^2
B=-8x
C=2
It’s like that because in quadratic equations A is always equals x^2(it can be any but in square, for instance 5x^2)

B is always x without square (for example 5x, 3x or x)

C is always a number it can be either negative or positive

Also Important thing is that if before a b c is minus which was written as 7x^2-8x+2 u can see before 8x is minus
So u gonna write b as -8x

I can’t see anything
