expand (3x+2y=9.5)(x+y)

expand

(3 x + 2 y = 9.5) (x + y)

3 x^{2} + 3 x y + 2 y = 9.5 y

Solution steps

(3 x + 2 y = 9.5) (x + y)

= (3 x + 2 \cdot 9.5 = y) (x + y)

Apply FOIL method:

(a + b) (c + d) = a c + a d + b c + b d

a = 3 x, b = 2 y = 9.5, c = x, d = y

3 xx + 3 x y + 2 y = 9.5 x + 2 y = 9.5 y

Expand

3 xx + 3 x y + 2 y : 3 x^{2} + 3 x y + 2 y

3 x^{2} + 3 x y + 2 y = 9.5 y

2 (x (x - 1))

(x - i)^{2} (x - 1 + i)^{2}

(x - 2 i) (x + 2 i) (x - 3 - i) (x - 3 + i)

2 (cot (x) - tan (x)) sin (2 x)

\frac{x ( x - 11 ) ^{2}}{( x + 6 ) ^{3}}
