expand (x^2-7x+10)+(-x+2)i

expand

(x^{2} - 7 x + 10) + (- x + 2) i

(x^{2} - 7 x + 10) + (- x + 2) i

Solution steps

(x^{2} - 7 x + 10) + (- x + 2) i

Apply rule:

(a) = a

(x^{2} - 7 x + 10) = x^{2} - 7 x + 10

= x^{2} - 7 x + 10 + (- x + 2) i

= x^{2} - 7 x + 10 + i (- x + 2)

Expand

i (- x + 2) : - x i + 2 i

= x^{2} - 7 x + 10 - x i + 2 i

Rewrite in standard complex form:

(x^{2} - 7 x + 10) + (- x + 2) i

= (x^{2} - 7 x + 10) + (- x + 2) i

2 (e + 1) (e - 1)

cos (t) u (t - 1)

3 (4^{x + 1})

- \frac{d}{d x} (e^{- x (α + \frac{β x}{2})})
