Question

How do I factor 14x^2-7xy-147y^2

Answer 1

STEP 1

Equation at the end of step

((14 • (x2)) - 7xy) - (3•72y2)

Equation at the end of step 2

((2•7x2) - 7xy) - (3•72y2)

STEP 3

STEP 4

Pulling out like terms

4.1 Pull out like factors :

14x2 - 7xy - 147y2 = 7 • (2x2 - xy - 21y2)

Trying to factor a multi variable polynomial :

4.2 Factoring 2x2 - xy - 21y2

Try to factor this multi-variable trinomial using trial and error

Found a factorization : (2x - 7y)•(x + 3y)
