Could you explain what this is?
Answer:
C and D
Step-by-step explanation:
The quadratic formula is
x= (-b±√b²-4ac)/2a
The formula uses the numerical coefficients in the quadratic equation.
The general quadratic equation is ax²+bx+c where a, b and c are the numerical coefficients
So, lets try and see;
A.
But due to the fact that in this equation you have x⁴, the equation is not a quadratic equation thus can not be solved using this formula
B
C
D.
From the checking above, the equations will be C and D
Answer:
13 and 2
Step-by-step explanation:
x+y=15
x-y=11
2x=26
x=13
13+y=15
y=2
