simplify 5-(x-1)/(x^2+3x-10)

simplify

5 - \frac{x - 1}{x ^{2} + 3 x - 10}

\frac{5 x ^{2} + 14 x - 49}{x ^{2} + 3 x - 10}

Solution steps

5 - \frac{x - 1}{x ^{2} + 3 x - 10}

Apply the fraction rule:

a - \frac{b}{c} = \frac{a c - b}{c}

= \frac{5 ( x ^{2} + 3 x - 10 ) - ( x - 1 )}{x ^{2} + 3 x - 10}

Simplify

5 (x^{2} + 3 x - 10) - (x - 1) : 5 x^{2} + 14 x - 49

= \frac{5 x ^{2} + 14 x - 49}{x ^{2} + 3 x - 10}
