Question

What is equivalent to -28x2 + 35x?

Answer 1

7x(-4x+5)

Multiplying: -56+35x

Explanation:

`\mathrm{Factor\:assuming\:x\ge-\\\infty}\\\:a^(b+c)=a^ba^c\\x^2 = xx\\-28xx+35x\\-7 * 4xx + 7 * 5x\\=7x\left(-4x+5\right)`

The only reason I had to assume x was any negative number was so that the absolute value did not matter in this instance, therefore making x become a negative number.

The other result, however, came from this:

`-28\cdot \:2=-56\\=-56+35x`

Inform me of any concerns. Hope this helps.

Answer 2

(35x) + (-56) this is an equivalent equation.
