Complete the table by providing justification for each step of the proof. Conjecture: If 4(x2 – 2) = 28, then x is 3 or –3
1 answer:
<span>4(x2 – 2) = 28
4x^2-8=28 Distributive law of multiplication
4x^2+8=28+8 Additive identity
4x^2=36 ; adding 8 to both sides
x^2 =9, dividing both sides by 4
x= +/- 3</span>
