Simplify: P + Q – (P – Q) + (2p – 3q)

Simplify: p + q – (p – q) + (2p – 3q)

Sum

p + q – (p – q) + (2p – 3q)

= p + q – p + q + 2p – 3q

= 2p – q

Exercise 11 (F) | Q 7

Write the coefficient of: xy in – 3axy

Write the degree of the following polynomial: – 8mn⁶+ 5m³n

In -5x³y²z⁴ ; write the coefficient of x³y. Also, write the degree of the given algebraic expression.

Add : 23y² , 8y² and – 12y²

Find the sum of: 4x²+ 8xy – 2y² and 8xy – 5y² + x²

Subtract the second expression from the first:

a² + ab + c², a² - d²

Common factor of 11pq², 121p²q³, 1331p²q is 11p²q².

On dividing `p/3` by `3/p`, the quotient is 9.

Factorise the following expression.

– xy – ay

Identify the numerical coefficient of term (other than constant) in the following expression:

x + 2xy + 3y
