Practice problem
Which of the following is not a step in factoring x4−28x2+196x^4 - 28x^2 + 196x4−28x2+196?
(x2)2−2×14×x2+142(x^2)^2 - 2\times 14\times x^2 + 14^2(x2)2−2×14×x2+142
(x2−14)(x2−14)(x^2 - 14)(x^2 - 14)(x2−14)(x2−14)
(x2+14)(x2−14)(x^2 + 14)(x^2 - 14)(x2+14)(x2−14)
(x2−14)2(x^2 - 14)^2(x2−14)2
Type a concept, like “slope” or “photosynthesis”.
