Test: Algebraic Expressions

coefficient is the integral number next to a given variable. 

for y, it is -3

In mathematics, a coefficient is a multiplicative factor in some term of a polynomial, a series, or any expression; it is usually a number, but may be any expression. So here the coefficient is z².

Three times of x is 3 multiplied by x which is 3x . sum of 3x and 11 is 3x plus 11 which is 3x + 11

Since father’s age is 3 times Raju's age and 5 more . So three times is 3x and 5 more, so it means 3x+5 is the answer.

Number of terms means the total number of individual elements present in a statement.

We have 4p²q, 3pq² and 5 separated by a plus or minus sign, so these three are our terms.

Sum of numbers is (a+b) , its product is ab and we have to subtract sum from product , so its ab-(a+b)

mn+5 – 2 + mn + 3 = mn + mn + 5 - 2+3 = 2mn+6
