Determine a so that 2a+1 a2+a+1
Weba2+2a+1 = (a+1)2 then, according to the law of transitivity, (a+1)2 = 0 We'll refer to this Equation as Eq. #4.2.1 The Square Root Principle says that When two things are equal, their square roots are equal. Note that the square root of (a+1)2 is (a+1)2/2 = (a+1)1 = a+1 Now, applying the Square Root Principle to Eq. #4.2.1 we get: a+1 = √ 0 WebSo we'll use the following inequality $$(a + 1)^2\ge 0$$ The equality will hold at $a=-1$, now this fits in fomain of $a$ $$a^2 + 2a + 1 \ge 0$$ Dividing by $a$ will alter the inequality …

WebExample 1: For the given matrix below compute both det (A) and det (2A). Also verify the property det (cA) = cn det (A). Solution: First of all, we’ll find the scalar multiples of the given matrix. The determinants: det (A) = 45 det (2A) = 360 = (8) (45) = 23det (A) Hence the property is verified. Example 2: Let A be an n × n matrix. WebFeb 28, 2012 · For 2a+1, a 2 +a+1, and 3a 2-3a+3 to be the consecutive terms in an A.P. their common difference should be the same. So, (a 2 +a+1) - (2a+1) = (3a 2-3a+3) - (a …
WebSo we'll use the following inequality. ( a + 1) 2 ≥ 0. The equality will hold at a = − 1, now this fits in fomain of a. a 2 + 2 a + 1 ≥ 0. Dividing by a will alter the inequality since it is a negative number. a + 2 + 1 a ≤ 0. So the actual inequation … Web3a-2a=a+2a=3a+5d+b. 5e+2e-4e=3e-7f+f=3e-6f+g. Hope it helps. 5.
