Maths Formulas For Class 8: Algebraic Identity
A linear equation in two variables has the maximum of two variables of order 2. It is depicted in the form of ax2 + bx + c=0
- (a + b)2 = a2 + 2ab + b2
- (a – b)2 = a2 – 2ab + b2
- (a + b) (a – b) = a2 – b2
- (x + a) (x + b) = x2 + (a + b)x + ab
- (x + a) (x – b) = x2 + (a – b)x – ab
- (x – a) (x + b) = x2 + (b – a)x – ab
- (x – a) (x – b) = x2 – (a + b)x + ab
- (a + b)3 = a3 + b3 + 3ab(a + b)
- (a – b)3 = a3 – b3 – 3ab(a – b)
Any number that can be written in the form of p ⁄ q where q ≠ 0 are rational numbers. It posses the properties of:
- Additive Identity: (a ⁄ b + 0) = (a ⁄ b)
- Multiplicative Identity: (a ⁄ b) × 1 = (a/b)
- Multiplicative Inverse: (a ⁄ b) × (b/a) = 1
Maths Formulas For Class 8: Laws of Exponents:
- a0 = 1
- a-m = 1/am
- (am)n = amn
- am / an = am-n
- am x bm = (ab)m
- am / bm = (a/b)m
- (a/b)-m =(b/a)m
- (1)n = 1 for infinite values of n.
1.Formula of Amount (Compounded Annually): A=P(1+R/100)t
P = Principal,
r = Rate of Interest, and
t = Time Period
2.Formula of Amount (Compounded Half Yearly): A=P(1+R/200)2t
R/2 = Half-yearly Rate,
2t = Number of Half-Years
