So before we can solve using the quadratic formula, we have to set the equation to zero. We can do that by adding 2 on both sides of the equation
Now we can use the quadratic formula, which is , with a=x^2 coefficient, b=x coefficient, and c=constant. We can form the equation as such:
Firstly, solve the exponents and the multiplications:
Next, do the addition within the radicals (these will be your exact solutions. but I'll solve for the decimal form as well.):
Next, solve for the rest on your calculator, and your answers will be (rounded to the thousandths) y = -0.463, 0.863
Answer:
9 is 11.345 ) 10 is 4.8 ) 11 is 1 cause your rounding to the hundreth ) 12 is 6. 327

Answer:
x =-9 y=2
Step-by-step explanation:
-4+2y=0
2y=4.
y=4/2
y=2
again
x+2y = -5
x+ 2* 2 = -5
x= -5 -4
x = -9
