Question

equations by factorisation
1. Find the roots of the following quadratic equations by far
(ii) 2x2+x-6=0
(1) X-3x - 10=0
(5) √2x² +7x+5√2 = 0
(V) 1002-20x + 1 = 0
(iv) 2x -x+ - = 0​

Answer 1

Answer:

$2 {x}^{2} + x - 6 = 2 {x}^{2} + 4x - 3x - 6 \\ = 2x(x + 2) - 3(x + 2) \\ = (2x - 3)(x + 2) \\ then \: either \: (2x - 3) \: or \: (x + 2) \: \\ should \: be \: 0 \\ so \\ roots \: are \: \frac{3}{2} \: ,- 2 \:$
