1.(x+4)(x+6)
= x(x+4)+6(x+4)
= x^2+4x+6x+24
= x^2+10x+24
2.(x-3)(x+8)
= x(x+8)-3(x+8)
= x^2+8x-3x-24
= x^2+5x-24
3.(2x+3)(3x-2)
=2x(3x-2)+3(3x-2)
=6x^2-4x+9x-6
=6x^2+5x-6
4.(t^2+5/2)(t^2-5/2) Of the form:a^2-b^2=(a+b)(a-b)
=t^4-25/4
= x(x+4)+6(x+4)
= x^2+4x+6x+24
= x^2+10x+24
2.(x-3)(x+8)
= x(x+8)-3(x+8)
= x^2+8x-3x-24
= x^2+5x-24
3.(2x+3)(3x-2)
=2x(3x-2)+3(3x-2)
=6x^2-4x+9x-6
=6x^2+5x-6
4.(t^2+5/2)(t^2-5/2) Of the form:a^2-b^2=(a+b)(a-b)
=t^4-25/4
