factor b^2-2b-3

factor

b^{2} - 2 b - 3

(b + 1) (b - 3)

Solution steps

b^{2} - 2 b - 3

Break the expression into groups

= (b^{2} + b) + (- 3 b - 3)

Factor out

b

from

b^{2} + b : b (b + 1)

Factor out

- 3

from

- 3 b - 3 : - 3 (b + 1)

= b (b + 1) - 3 (b + 1)

Factor out common term

b + 1

= (b + 1) (b - 3)

\frac{1}{1 + ( 0.7 ) ^{2}}

\frac{( 2 c d ^{4} ) ^{4}}{( 2 c ^{2} d ^{3} ) ^{2}}

4 x^{2} + 15 x + 9

18 s + 22 = - 14

\frac{25 - b}{- 2} = 10
