PLS HELP!! Find the area of the shaded region. https://dlap.gradpoint.com/Resz/~yUA6AAAAAAwvJCB1d39fWB.cHNpEWkQ1EvzQcLCssJd3B/7234256,CB6/Assets/questions/quiz/algebra_1/al1mubin/IMG11038x.jpg

Area is found by: \(\large\bf{A=b \times h}\) This means you need to find the area of both the shaded region and the unshaded region by means of the formula. \(\large\bf{A=(2x +2) \times (3x-4)}\) \(\large\bf{A=(x-3) \times (x-6)}\) Can you simplify those?

eviant:

6x^2-2x-8 for the 1st one?

563blackghost:

yep

eviant:

and x^2-9x+18 for the 2nd one?

563blackghost:

Correct. Now you just need to subtract the two.

eviant:

12x^3-x^2-9x+10

563blackghost:

Not quite. \(\large\bf{(6x^{2}-x^{2}) - (2x - 9x) - (8+18)}\)

eviant:

5x^2+7x-20

563blackghost:

close the last term would be 26. \(\large\bf{5x^{2} + 7x - 26}\)
