Answers
Step-by-step explanation:
1. (i.) 3x + 7 = 2 terms = binomials
(ii.) 5xyz = 1 term = monomial
(iii.) 7ab - 3c + 9 = 3 terms = trinomials
2. Q = 4xx - 7x + 2xx + 4x - 3
value of x = -1
So, the answer will be:
= [4(-1)(-1)] - [7(-1)] + [2(-1)(-1)] + [4(-1)] - 3
= 4 - (-7) + 2 + (-4) - 3
= 4 + 7 + 2 - 4 - 3
= 13 - 4 - 3
= 13 - 7
= 6
Answer:
Step-by-step explanation:
1.
i) 3x + 7 has two terms.
ii) 5xyz has only one term.
iii) 7ab - 3c + 9 has three terms.
2. 6
Step-by-step explanation:

ii) 5xyz has only one term.
iii) 7ab - 3c + 9 has three terms.
2.
SIMPLIFY 4x² - 7x + 2x² + 4x - 3, find the value of x = -1.
Solution:-
Let the polynomial be p(x) = 4x² - 7x + 2x² + 4x - 3
To find:-
Value at p(-1) = ?
Procedure:-
Extra Information:-
Polynomials : Polynomial are variable based dialect in the language of maths.
In a common language , polynomials are defined as a string of variables and numbers put together.
Highest power of a polynomial is called degree of polynomial.
A constant polynomial is nothing but a monomial with degree zero.
Equation: A condition or a constraint placed on x and y coordinates.
Curve: A union of points that satisfy a particular condition.
Remainder theorem: When p(x) is divided by (x - a) then the remainder is given by p(a).
