Question

Choose the quadratic equation that has a leading coefficient of 8 and solutions -10 and 7/8

Answer 1

`f(x)=8x^2+73x-70`

Explanation:

We are given

zeros as -10 and 7/8

now, we can set up function as

`f(x)=a(x-(-10))(x-(7)/(8))`

now, we are given that

leading coefficient is 8

so, a=8

now, we can plug it

`f(x)=8(x-(-10))(x-(7)/(8))`

now, we can simplify it

`f(x)=8\left(x^2+(73x)/(8)-(35)/(4)\right)`

so, we get

`f(x)=8x^2+73x-70`
