Recognize as quadratic form: Recognize the polynomial as a quadratic in form.The given polynomial 6x4−17x2t2+10t4 can be seen as a quadratic in terms of x2, where x2 is the variable and t2 is a constant.
Factor using middle term: Factor the quadratic polynomial using the middle term factor method.We need to find two numbers that multiply to (6x2)(10t2)=60x2t2 and add up to −17x2t2. The numbers that satisfy these conditions are −12x2t2 and −5x2t2.
Rewrite by splitting: Rewrite the polynomial by splitting the middle term. 6x4−17x2t2+10t4=6x4−12x2t2−5x2t2+10t4
Factor by grouping: Factor by grouping.Group the terms to factor by grouping:(6x4−12x2t2)−(5x2t2−10t4)Now factor out the common factors from each group:6x2(x2−2t2)−5t2(x2−2t2)
Factor out common factor: Factor out the common binomial factor.The common binomial factor is (x2−2t2), so we factor it out:(6x2−5t2)(x2−2t2)
Recognize difference of squares: Recognize that (x2−2t2) is a difference of squares and can be further factored.(x2−2t2) can be written as (x2−(2t)2), which is a difference of squares and can be factored as:(x−2t)(x+2t)
Write final factorization: Write the final factorization.The complete factorization of the polynomial is:(6x2−5t2)(x−2t)(x+2t)
