Question

show that \[2x ^{2}[x \times(-1)+(3-x)] -x(3-x)(4x) \over (2x ^{2})^{2}\] can reduce to \[-3 \over 2x ^{2}\]

Answer 1

2x^2(-x+3-x)-4x^2(3-x) all over 4x^4
2x^2(-2x+3)-12x^2+4x^3 all over 4x^4
-4x^3+6x^2-12x^2+4x^3 all over 4x^4
-4x^3+4x^3-12x^2 all over 4x^4
-12x^2/(4x^4)
-3/2x^2

Answer 2

thank you again lol! would you possibly know how simplify\[[-(a+h)^{3}-4(a+h)^{2} +2(a+h) +3] - [-a ^{3}-4a ^{2} + 2a+3] \over h\]
