Factorizacion de los trinomios

3x-70+x²=

-8d+d²+15=

45+146+b²=

x-20-x²=

b²-5b-36=

-16+z²+6z=

56+k²-15k=

-8t+16+t²=

??

Answer 1

${x^2+3x-70=}\\{(x+10)(x-7)}\\ \\{ d^2-8d+15=}\\{(d-3)(d-5)}\\ \\{x^2-x+20=}\\{(x-5)(x+4)}} \\ \\{b^2-5b-36=}\\{(b-9)(b+4)}\\\\{z^2+6z-16=}\\{(z+8)(z-2)}\\\\{k^2-15k+56=}\\{(k-8)(k-7)}\\\\{t^2-8t+16=}\\{(t-4)^2}$

Salu2. :)
