Respuesta

−64+43+412+20−14

Explicación paso a paso:

( − 3 ^ 2 − 4 + 2 ) (x+ 2 ^2-5x-7)

(−3^2−4+2)(-4x+2^2−7)

(−3x2−4x+2)(2x2−4x−7)

−3(22−4−7)⋅2−4(22−4−7)+2(22−4−7)

−3(2x2−4x−7)⋅x2−4x(2x2−4x−7)+2(2x2−4x−7)

−64+123+212−4(22−4−7)+2(22−4−7)

−6x4+12x3+21x2−4x(2x2−4x−7)+2(2x2−4x−7)

−64+123+212−83+162+28+2(22−4−7)

−6x4+12x3+21x2−8x3+16x2+28x+2(2x2−4x−7

−64+123+212−83+162+28+42−8−14)

−6x4+12x3+21x2−8x3+16x2+28x+4x2−8x−14

−64+43+212+162+28+42−8−14

−6x4+4x3+21x2+16x2+28x+4x2−8x -14

−64+43+412+28−8−14

−6x4+4x3+41x2+28x−8x−14

−64+43+412+20−14

Solución: −64+43+412+20−14
