Need some (: ! consider the quadratic equation below. (4x+z)(3x-w)=0 if w=21, determine an x-intercept of the parabola represented by this equation. a) (21,0) b) (-7,0) c) (-21,0) or d) (7,0)

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.

Ithink it's the first one ( let me know if it right)
