The quadratic formula is (-b+-sqrt(b^2-4ac))/(2a)
In your equation,
A=2
B=-10
C=7
Plugging these in we get
(10+-sqrt(100-4(2)(7)))/(2*2)
=(10+-sqrt(44))/4
=(10+-6.633)/4
=16.633/4 or -3.366/4
=4.158 or -0.841
Final Answer:
x=4.158 or x=-0.841
Hope I helped :)
Answer:
z=4
Step-by-step explanation:
subtract 47-35
3z=12
divide both sides by 3
z=4
The GCF of a polynomial is the greatest factor which is common to all the terms of the polynomial.
Thus, an example of a polynomial with a GCF of 7 is
The above polynomial can also be rewritten as
This form of the polynomial is obtained by factoring out the GCF of the polynomial.
For second one the answer is 14
