Question

18asquare-50 factorise​

Answer 1

Step-by-step explanation:

It is Given That,

$18 {a}^{2} - 50$

So we have To factorise It ,

We know ,

The quadratic formula is ,

$a = \frac{ - b \frac{ + }{} \sqrt{ {b}^{2} - 4xc} }{2x}$

Here, in the Eqn.

X=18 and b=-50 and c=0

Now putting the Values of x,b,c in quadratic Formula,

We get,

$a = \frac{50 \frac{ + }{} \sqrt{ ({50})^{2} - 4 \times 18 \times 0 } }{2 \times 18}$

$a = \frac{50 \frac{ + }{} \sqrt{ ({50})^{2} } }{36}$

We get ,

$a = \frac{50 + 50}{36} \: \: or \: \frac{50 - 50}{36}$

$a = \frac{100}{36} \: \: \: or \: \: \frac{0}{36}$

$a = 2.7 \: \: or \: \: 0$

Hope it helps you!!
