1.(a+3)(a+2)

=(a+3)(a+2)

=(a)(a)+(a)(2)+(3)(a)+(3)(2)

=a2+2a+3a+6

=a2+5a+6

(a+2)(a+3)

2.(7x2−5)(7x2−1)

=(7x2+−5)(7x2+−1)

=(7x2)(7x2)+(7x2)(−1)+(−5)(7x2)+(−5)(−1)

=49x4−7x2−35x2+5

=49x4−42x2+5

=(7x2−1)(7x2−5)

3.=(b+5)(b+−7)

=(b)(b)+(b)(−7)+(5)(b)+(5)(−7)

=b2−7b+5b−35

=b2−2b−35

4. x^2+3√2)(x^2+5√2)

=x4+11.313708x2+30

5  

(√10−8)(√10+5)

=−30−3√10(Decimal: -39.486833)

6.=(a+4)*(a+4)*(a+4)

=(a+4)(a2+8a+16)

=(a)(a2)+(a)(8a)+(a)(16)+(4)(a2)+(4)(8a)+(4)(16)

=a3+8a2+16a+4a2+32a+64

=a3+12a2+48a+64

6.=(a+4)*(a+4)*(a+4)

=(a+4)(a2+8a+16)

=(a)(a2)+(a)(8a)+(a)(16)+(4)(a2)+(4)(8a)+(4)(16)

=a3+8a2+16a+4a2+32a+64

=a3+12a2+48a+64

7.=(3a−2)*(3a−2)*(3a−2)

=(3a+−2)(9a2+−12a+4)

=(3a)(9a2)+(3a)(−12a)+(3a)(4)+(−2)(9a2)+(−2)(−12a)+(−2)(4)

=27a3−36a2+12a−18a2+24a−8

=27a3−54a2+36a−8

8.

(a2−b3)3

=(a2−b3)*(a2−b3)*(a2−b3)

=(a2+−b3)(b6+−2a2b3+a4)

=(a2)(b6)+(a2)(−2a2b3)+(a2)(a4)+(−b3)(b6)+(−b3)(−2a2b3)+(−b3)(a4)

=a2b6−2a4b3+a6−b9+2a2b6−a4b3

=−b9+3a2b6−3a4b3+a6

9.

(x−2a)3

=(x−2a)*(x−2a)*(x−2a)

=(x+−2a)(4a2+−4ax+x2)

=(x)(4a2)+(x)(−4ax)+(x)(x2)+(−2a)(4a2)+(−2a)(−4ax)+(−2a)(x2)

=4a2x−4ax2+x3−8a3+8a2x−2ax2

=−8a3(t5+2t3)3

=(t5+2t3)*(t5+2t3)*(t5+2t3)

=(t5+2t3)(t10+4t8+4t6)

=(t5)(t10)+(t5)(4t8)+(t5)(4t6)+(2t3)(t10)+(2t3)(4t8)+(2t3)(4t6)

=t15+4t13+4t11+2t13+8t11+8t9

=t15+6t13+12t11+8t9

+12a2x−6ax2+x3

10.
