Question

Factorise the given equation completely 6 X square + 7 x minus 5

Answer 1

Answer:

6x²+7x-5=0

6x²+10x-3x-5=0

2x(3x+5)-1(3x+5)=0

(3x+5) (2x-1) =0

3x+5 =0 or 2x-1=0

3x=-5 or 2x=1

x= -5/3 or x=1/2

Answer 2

Answer:

$6x {}^{2} + 7x - 5 = 0 \\ \geqslant first \: we \: have \: to \: split \: the \: midde \: \: term \: \\ \geqslant {6x}^{2} - 3x + 10x - 5 = 0 \\ \geqslant 3x(2x - 1) + 5(2x - 1) = 0 \\ \geqslant (3x + 5) \: (2x - 1) \\ \geqslant (3x + 5) = 0 \:(2x - 1) = 0 \\ \geqslant x = \frac{ -5}{3} \: \: \: \: \: y = \frac{1}{2}$
