Question

10b2 +17b + 3

Answer 1

\[{-17 \pm \sqrt{17^2 - 4(10 \times 3)} \over (2 \times 10)}\]

Answer 2

\[(2 b+3) (5 b+1)\]

Answer 3

= 10b^2 + 2b + 15b + 3
= 2b(5b+1) + 3(5b+1)
= (2b+3)(5b+1)

Answer 4

\[b = {-17 \pm 13 \over 20} = {-4 \over 20} or {30 \over 20} = {-1 \over 5} or {3 \over 2}\]
