Simplify a - {b-[c-(d-e) - 1 - g).
o a + b + c + d + e-f+g
a-b+ c-d + e-f+g
a + b + c-d + e-f+g
a-b+ c-d + e +f-g

After being rearranged and simplified, which of the following equations could be solved using the quadratic formula? check all that apply. a. 9% + 3x2 = 14 + x-1 b. -x+ + 4x + 7 = -32-9 c. 5x + 4 = 3x4 - 2 d. 2x2 + x2 + x = 30

100 points, hi, i’m not sure what to do here,the data doesn’t seem to be quadratic .? can anyone me, in advance
