simplify (x-4)(x+4)-(x-3)(x+3)+3x+10

simplify

(x - 4) (x + 4) - (x - 3) (x + 3) + 3 x + 10

3 x + 3

Solution steps

(x - 4) (x + 4) - (x - 3) (x + 3) + 3 x + 10

Expand

(x - 4) (x + 4) : x^{2} - 16

= x^{2} - 16 - (x - 3) (x + 3) + 3 x + 10

Expand

- (x - 3) (x + 3) : - x^{2} + 9

= x^{2} - 16 - x^{2} + 9 + 3 x + 10

Group like terms

= x^{2} - x^{2} + 3 x - 16 + 9 + 10

Add similar elements:

x^{2} - x^{2} = 0

= 3 x - 16 + 9 + 10

Add the numbers:

- 16 + 9 + 10 = 3

= 3 x + 3

x^{2} - 6 \cdot + 9

3 \frac{5}{6} \cdot 2

\frac{x ^{x}}{x}

(x - 4)^{2}

\frac{1}{8} - (- \frac{3}{4})
