Multiply these binomials: (6x + 7)(20x – 9)=
**Weegy:** (6x + 7)(20x ? 9) = 120x^2 + 86x - 63. **User:** Multiply these binomials: (10x – 11)(–14x + 9)
**Weegy:** (10x ? 11)(?14x + 9) = -140x^2 + 244x - 99. **User:** Multiply these binomials: (16x + 13)(–8x + 15)=
**Weegy:** (16x ? 19)(8x ? 8) = 128x^2 - 280x + 152. **User:** Multiply these binomials: (6x – 3)(–5x + 2)=
**Weegy:** x=-1 and x=-1/5 for the equation 5x^2+6x=-1 **User:** Multiply these binomials: (18x + 20)(–12x – 6)=

(6x + 7)(20x – 9)

= 120x^2 - 54x + 140x - 63

= 120x^2 + 86x - 63

= 120x^2 - 54x + 140x - 63

= 120x^2 + 86x - 63

(10x – 11)(–14x + 9)

= -140x^2 + 90x + 154x - 99

= -140x^2 + 244x - 99

= -140x^2 + 90x + 154x - 99

= -140x^2 + 244x - 99

(16x + 13)(–8x + 15)

= -128x^2 + 240x - 104x + 195

= -128x^2 + 136x + 195

= -128x^2 + 240x - 104x + 195

= -128x^2 + 136x + 195

(6x – 3)(–5x + 2)

= -30x^2 + 12x + 15x - 6

= -30x^2 + 27x - 6

= -30x^2 + 12x + 15x - 6

= -30x^2 + 27x - 6
