1. Joe is using the quadratic formula to solve a
quadratic equation as shown. Which equation
is he solving?
x=3 V(-3) 2= 4( 2) (7)
2(2)
A. 0 = 2x2 – 3x + 7
B. 0 = 2x2 + 3x +7
C. 0 = – 3x2 + 2x + 7
D. O = 3x² + 2x + 7

answer:  

step-by-step explanation:

odd numbers are only divisible by 1 and itself.

even numbers are divisible by more than 1 and itself.

for example 6 is even because it is divisible by more than 1 and its self. 1 x 6= 6 ; 2 x 3= 6

and 7 is odd because only 7 x 1 equals seveb
