Answer:

x = -5   & x = -2

Step-by-step explanation:

x^2 + 7x +10 = 0  you takeaway 9 as quadratic equations have to equal 0

(x+5)(x+2) = 0    you find 2 numbers that go into 10 that add to make 7 and multiply to make 10

(x+5) = 0 so x =-5     &   (x+2) = 0 so x =-2

Does anyone know how to do this ??
Mashcka [7]
2(3 exponent 2) + 4(3)(5) follow my equation and you should get your answer. all you have to do is replace the letters in the formula in the needed numbers. For instance s= 3 and h=5 , therefore you replace the s in the formula to a 3 and the h in the formula to a 5

You're too shy to say it

Inside, we both know what's been going on

We know the game and we're gonna play it

And if you ask me how I'm feeling
