Question

Simplify-: (2x+y)(1+4x+3y)-6x(x-y)​

Answer 1

Answer:

(a) 17 = x + 7 (b) (t - 7) > 5 (c) 2 = 2

(d) (7 3) - 19 = 8 (e) 5 x 4 - 8 = 2 x (f) x - 2 = 0

(g) 2m < 30

(h) 2n + 1 = 11 (i) 7 = (11 x 5) - (12 x 4)

(j) 7 = (11 x 2) + p (k) 20 = 5y

<5

(n) 20 - (10-5) = 3 x 5

(m) z + 12 > 24

(0) 7-X= 5

Answer 2

Simplify :- (2x+y)(1+4x+3y)-6x(x-y)

$\sf =( 2x + y)(1 + 4x + 3y) - 6x(x - y)$

$\sf = 2x(1 + 4x + 3y) + y(1 + 4x + 3y) - 6 {x}^{2} + 6xy$

$\sf = 2x + 8 {x}^{2} + 6xy + y + 4xy + 3 {y}^{2} - 6 {x}^{2} + 6xy$

$\sf= 2 {x}^{2} + 16xy + 3 {y}^{2} + 2x + y$
