Answer:7/5, -1
Step-by-step explanation:
all quadratic equations have 2 roots so meaning it is factorized into to bracts so first step
(5y )(y )
the reason there is a five before one of the y's is because the a in our function {ax^2+bx+c}
second step is to factorize so u think what 2 numbers are equal to -7 when multiplied. since 7 is a prime number its either 7 and -1 or -7 and 1
so u try both factors to check the middle term
first one
(5y+7)(y-1)
that would be equal to 5y^2+2y-7 which isn't the function we are looking for therefore the
second one (5y-7)(y+1)
that would be equal to 5y^2-2y-7 which is correct
