Question

x square - 70x+1225​

Answer 1

Answer:

x=35

Step-by-step explanation:

${x}^{2} - 70x + 1225$

$a {x}^{2} + bx + c$ (general form)

Here,

$a = 1$

$b = - 70$

$c = 1225$

We know that,

(Quadratic formula)

$\color{red}{{\boxed{x = \frac{ - b ± \sqrt{ {b}^{2} - 4ac } }{2a}}}}$

$x = \frac{ - ( - 70) ± \sqrt{ ({ - 70})^{2} - 4(1)(1225) } }{2(1)}$

$x = \frac{70 ± \sqrt{4900 - 4900} }{2}$

$x = \frac{70 ± \sqrt{0} }{2}$

$x = \frac{70}{2}$

$x = 35$

Therefore,it has identical solution i.e 35.We will identical(same)solution when discriminant(${b}^{2}-4ac$)is 0.

HOPE THAT HELPS!!
