Answer:
[tex]3x^4-2x^3-15x^2+14x[/tex]
Step-by-step explanation:
[tex](x^2 - 2x)(3x^2 + 4x - 7)[/tex]
To find equivalent expression we multiply each term in first parenthesis with each term in second parenthesis
Multiply x^2 inside second parenthesis
[tex]x^2(3x^2 + 4x - 7)= 3x^4+4x^3-7x^2[/tex]
[tex]-2x(3x^2 + 4x - 7)=-6x^3-8x^2+14x[/tex]
now we keep all the terms together
[tex]3x^4+4x^3-7x^2-6x^3-8x^2+14x[/tex]
Now we combine like terms
[tex]3x^4-2x^3-15x^2+14x[/tex]
