$f\left(x\right)=\left(5x^4\right)^3+9\left(5x^4\right)^2x^2-12\left(5x^4\right)^2+\left(3x^2\right)^3+15x^4\left(3x^2\right)^2-12\left(3x^2\right)^2-64+240x^4+144x^2-360x^4x^2$
Learn how to solve expressions algébriques problems step by step online. f(x)=(5x^4+3x^2+-4)^3. Apply the formula: \left(a+b+c\right)^3=a^3+3a^2b+3a^2c+b^3+3ab^2+3b^2c+c^3+3ac^2+3bc^2+6abc, where a=5x^4, b=3x^2 and c=-4. Apply the formula: x^mx^n=x^{\left(m+n\right)}, where m=4 and n=2. Apply the formula: \left(ab\right)^n=a^nb^n, where a=3, b=x^2 and n=2. Apply the formula: \left(ab\right)^n=a^nb^n.
