simplify sqrt(9a^2)+sqrt(49b)-a+sqrt(b)

simplify

9 a^{2} + 49 b - a + b

8 b + 2 a

Solution steps

9 a^{2} + 49 b - a + b

9 a^{2} = 3 a

49 b = 7 b

= 3 a + 7 b - a + b

Group like terms

= 7 b + b + 3 a - a

Add similar elements:

7 b + b = 8 b

= 8 b + 3 a - a

Add similar elements:

3 a - a = 2 a

= 8 b + 2 a

\frac{x ^{2} - 64}{4 x ^{3} + 32 x ^{2}}

(3 a^{2} - a + 2)^{2}

\frac{( 18 x ^{3} + 12 x ^{2} - 3 x )}{6 x ^{2}}

3 + (- \frac{3}{2})

e^{l n (x - 1)}
