Quizplus · Accepted Answer

The Answer of Perform the indicated operations.
(a) $\left(x^{2}-5 x+2\right)+\left(2 x-3 x^{2}\right)-2 x(2 x+1)$
(b) $(6-5 x)^{2}$
(c) $(r+3)\left(2 r^{2}+9 r-5\right)$
(d) $(2 t-5)(5+2 t)$
(e) $[3 y+(4-2 y)]^{2}$

Perform the Indicated Operations (x2−5x+2)+(2x−3x2)−2x(2x+1)\left(x^{2}-5 x+2\right)+\left(2 x-3 x^{2}\right)-2 x(2 x+1)(x2−5x+2)+(2x−3x2)−2x(2x+1) (B) (6−5x)2(6-5 x)^{2}(6−5x)2

Perform the Indicated Operations $\left(x^{2}-5 x+2\right)+\left(2 x-3 x^{2}\right)-2 x(2 x+1)$ (B) $(6-5 x)^{2}$
