The picture above contains some math sums.​

Answer 1

Question:-

• Factorise the polynomials.

Solution:-

$\sf 2 {x}^{2} - 7x + 6$

$\sf = 2 {x}^{2} - 4x - 3x + 6$

$\sf = 2x(x - 2) - 3(x - 2)$

$\sf = (2x - 3)(x - 2)$

Hence, factorised form is (2x-3)(x-2)

$\sf {x}^{3} - 25x$

$\sf = x( {x}^{2} - 25)$

$\sf = x( {x}^{2} - {5}^{2} )$

$\sf = x(x + 5)(x - 5)$

Hence,the factorised form is x(x+5)(x-5)

$\sf {a}^{2} + 10a + 24$

$\sf = {a}^{2} + 4a + 6a + 24$

$\sf = a(a + 4) + 6(a + 4)$

$\sf = (a + 4)(a + 6)$

Hence, the factorised form is (a+4)(a+6)
