Simplify (x-3)(x^2+7x-8)

Mathematics
1 answer:
klio [65]3 years ago

A common way to simplify this problem would be to use an area model, or the distributive property. Using the distributive property does not require any drawing, so here goes.
(x-3)(x²+7x-8)   Distribute by multiplying each of the terms in the first set of parentheses by every term in the second set of parentheses.
x³+7x³-8x-3x²-21x+24   Then combine alike terms.
8x³-3x²-29x+24    Is your final answer.

Can you conclude that the figures are congruent? Justify your answers.
Fantom [35]
Since I can’t see the figure I would have to assume that if they are the same shape and size then, yes they’re congruent.
