Answer to: Check whether the following are quadratic equations: (i) (x + 1)^2 = 2(x – 3) (ii) x^2 – 2x = (–2) (3 – x)

(i) Given, (x + 1)2 = 2(x – 3) By using the formula for (a + b)2 = a2+ 2ab +b2 ⇒ x2 + 2x + 1 = 2x – 6 ⇒ x2 + 7 = 0 Since the above equation ...

Answer to: ABCD is a cyclic quadrilateral Figure. Find the angles of the cyclic quadrilateral.

It is known that the sum of the opposite angles of a cyclic quadrilateral is 180o Thus, we have ∠C +∠A = 180 4y + 20− 4x = 180 − 4x + 4y = 160...

Answer to: Solve the pair of linear equations: 152x − 378y = − 74 76x − 189y = − 37

x =(189y-137)/76……………..…(i) − 378x + 152y = − 604 − 189x + 76y = − 302 ………….. (ii) Using the value of x in equation (ii), we get −189(189y−37/...

Answer to: (a – b)x + (a + b) y = a^2 – 2ab – b^2 (a + b)(x + y) = a^2 + b^2

(a + b) y + (a – b) x = a2− 2ab − b2 …………… (i) (x + y)(a + b) = a2 + b2 (a + b) y + (a + b) x = a2 + b2 ………………… (ii) Subtracting equation (ii)...
