WebKnown matrix A=[[3,a+2b],[2a+3b,4]];B=[[1,4],[6,5]] and C= [[4,10],[20,9]] If A+B=C, then determine the value of 3a-2b ! This problem has been solved! You'll get a detailed solution from a subject matter expert that helps you learn core concepts. Web(a+1) • (2a-1) Which is the desired factorization. Equation at the end of step 2 : (2a - 1) • (a + 1) = 0 Step 3 : Theory - Roots of a product : 3.1 A product of several terms equals zero. When a product of two or more terms equals zero, then at least one of the terms must be zero. ... ± 3 • √ 1 = ± 3 So now we are looking at: a ...

WebQuestion: Show that if a square matrix A satisfies the equation A 2 + 2 A + I = 0, then A must be invertible. My work: Based on the section I read, I will treat I to be an identity matrix, which is a 1 × 1 matrix with a 1 or as an square matrix with main diagonal is all ones and the rest is zero. I will also treat the O as a zero matrix, which ... 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 … WebMar 16, 2024 · Davneet Singh has done his B.Tech from Indian Institute of Technology, Kanpur.
