factor r^2+3r-10

factor

r^{2} + 3 r - 10

(r - 2) (r + 5)

Solution steps

r^{2} + 3 r - 10

Break the expression into groups

= (r^{2} - 2 r) + (5 r - 10)

Factor out

r

from

r^{2} - 2 r : r (r - 2)

Factor out

5

from

5 r - 10 : 5 (r - 2)

= r (r - 2) + 5 (r - 2)

Factor out common term

r - 2

= (r - 2) (r + 5)

3 (\frac{π \cdot 0. 2 ^{2}}{4}) + 2 (\frac{π \cdot 0.1 6 ^{2}}{4})

\frac{( 5 ^{8} ) ^{2} \cdot 5 ^{7}}{5 ^{22}}

\frac{1}{32}

\frac{\frac{x ^{2} + 6 x - 7}{3 x ^{2}}}{\frac{x + 7}{6 x}}

1. 3^{2} + 3.2 x^{0.7}
