Question

which expression is equivalent to (x^2 - 2x)(3x^2 + 4x - 7)

Answer 1

Answer:

$3x^4-2x^3-15x^2+14x$

Step-by-step explanation:

$(x^2 - 2x)(3x^2 + 4x - 7)$

To find equivalent expression we multiply each term in first parenthesis with each term in second parenthesis

Multiply x^2 inside second parenthesis

$x^2(3x^2 + 4x - 7)= 3x^4+4x^3-7x^2$

$-2x(3x^2 + 4x - 7)=-6x^3-8x^2+14x$

now we keep all the terms together

$3x^4+4x^3-7x^2-6x^3-8x^2+14x$

Now we combine like terms

$3x^4-2x^3-15x^2+14x$
