Solve the equation with quadratic formula
y^2+3y-10=0

y = 2 and y = -5

Step-by-step explanation:

Because the coefficient is not greater than 1, you can simply solve the problem without the quadratic formula.

By using the "x" method, you must figure out what multiplies to give you -10, and adds to give you 3

So, you find your values as 5 and -2. You then set these values equal to zero in terms of Y. As so (y+5)=0 and (y-2)=0

Then, you solve out to get your answer! Y is equal to -5 and 2

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
