Multiply (2x^2-3x+5)(x^2+4x+1)

a- 3x^2+x+6
b- 2x^4+5x^3-5x^2+17x+5
c- 2x^4+2x^2-12x+5
d- 2x^4-12x^2+5

Can someone check if i did this right since i really want to make sure it’s correct. if you do you so much

The first few steps in solving the quadratic equation 9x2 + 49x = 22 ? 5x by completing the square are shown. 9x2 + 49x = 22 ? 5x 9x2 + 54x = 22 9(x2 + 6x) = 22 which is the best step to do next to solve the equation by completing the square? 9(x2 + 6x + 3) = 25 9(x2 + 6x + 3) = 49 9(x2 + 6x + 9) = 31 9(x2 + 6x + 9) = 103
