Q. 1 A5.0( 2 Votes )

Solve the followi

Class 10th Tamil Nadu Board - Math 3. Algebra

Answer :

x² + 6x – 7 = 0

= x² + 6x = 7

Add 9 on both sides

= x² + 6x + 9 = 7 + 9

= x² + 2(3)(x) + 3² = 16

= (x + 3)² = 16

= x + 3 = √16

= x + 3 = ± 4

x + 3 = 4 or x + 3 = –4

x = 4 – 3 or x = – 4 – 3

x = 1 or x = – 7
