Question

EXERCISE- 15.1
Solve these sums :
1. x2 – 3x + 2 = 0
3. 2x² – 3x+1=0
5. x(x - 2) = 9 - 2x
7. 4y = 11y+ 3
2. x2 + 6 = 5x
4. 2y = 12 - 5y
6. x2 + 7x = 44
8. (2a + 1) (a + 3) + 3 = 0​

Answer 1

$1.x {}^{2} - 3x + 2$

$x ^{2} - x - 2x + 2$

$x(x - 1) - 2(x - 1)$

$(x - 1)(x - 2)$

$x = 1 \: and \: 2$
