Use suitable identities to find the following product: (x + 4) (x + 10)

Open in App

Solution

Using identity, (x + a) (x + b) = $x^{2}$ + (a+b)x + ab
(x + 4)(x + 10) = $x^{2}$ + (4+10)x + (4)(10) = $x^{2}$ + 14x + 40

Using identity, (x + a) (x + b) = x2 + (a+b)x + ab (x + 4)(x + 10) = x2 + (4+10)x + (4)(10) = x2 + 14x + 40

Using identity, (x + a) (x + b) = $x^{2}$ + (a+b)x + ab
(x + 4)(x + 10) = $x^{2}$ + (4+10)x + (4)(10) = $x^{2}$ + 14x + 40
