Answer:

Explanation:
Simplify or expand:
×

Multiply the monomials:
3(x-2)+4(x-2)-15(x-2)(x-2)+4(x-2)-5(x-2)
Apply the Distributive Property:
3x-3×2+4(x-2)-15(x-2)(x-2)+4(x-2)-5(x-2)
3x-3×2+4x-4×2-15(x-2)(x-2)+4(x-2)-5(x-2)
3x-3×2+4x-4×2+(-15x-15×(-2))(x-2)+4(x-2)-5(x-2)
3x-3×2+4x-4×2+(-15x-15×(-2))(x-2)+4x-4×2-5(x-2)
3x-3×2+4x-4×2+(-15x-15×(-2))(x-2)+4x-4×2-5x-5×(-2)
Determine the sign for multiplication or division:
3x-3×22+4x-4×2+(-15x+15×2)(x-2)+4x-4×2-5x-5×(-2)
3x-3×2+4x-4×2+(-15x+15×2)(x-2)+4x-4×2-5x+5×2
Calculate the product or quotient:
3x-6+4x-4×2+(-15x+15×2)(x-2)+4x-4×2-5x+5×2
3x-6+4x-8+(-15x+15×2)(x-2)+4x-4×2-5x+5×2
3x-6+4x-8+(-15x+30)(x-2)+4x-4×2-5x+5×2
3x-6+4x-8+(-15x+30)(x-2)+4x-8-5x+5×2
3x-6+4x-8+(-15x+30)(x-2)+4x-8-5x+10
Apply the Distributive Property
3x-6+4x-8-15x(x-2)+30(x-2)+4x-8-5x+10
3x-6+4x-8-15x×x-15x×(-2)+30(x-2)+4x-8
3x-6+4x-8-15x×x-15x×(-2)+30x-30×2+4x-8-5x+10
Determine the sign for multiplication or division:
3x-6+4x-8-15x×x+15x×2+30x-30×2+4x-8-5x+10
Multiply the monomials:
3x-6+4x-8-
+15x×2+30x-30×2+4x-8-5x+10
3x-6+4x-8-
+30x+30x-30×2+4x-8-5x+10
Calculate the product or quotient:
3x-6+4x-8-
+30x+30x-60+4x-8-5x+10
Reorder and gather like terms:
(3x+4x+30x+30x+4x-5x)×x+(-6-8-60-8+10)

Collect coefficients of like terms:
(3+4+30+30+4-5)×x+(-6-8-60-8+10)

Calculate the sum or difference:
(7+30+30+4-5)×x+(-6-8-60-8+10)

(37+30+4-5)×x+(-6-8-60-8+10)

(67+4-5)×x+(-6-8-60-8+10)

(71-5)×x+(-6-8-60-8+10)

66x+(-6-8-60-8+10)

66x+(-14-60-8+10)

66x+(-74-8+10)

66x+(-82+10)

66x-72

Rewrite the expression:
+66x-72
