Step-by-step explanation:

$(9 - 2) ^{2} - (2 ^{2} - 3 ^{2} ) + 2$

calculate the powers behind the brackets from left to right

$(49) ^ - (4 - 9 ) + 2$

Calculate the powers (a power squared means the number times itself so 2 squared equals 4)

$49 - - 5+2$

Calculate the sum ( minus minus equals plus so for example 4- -5= 4+5=9)

4- 49+5+2= 56

Answer: 56

Step-by-step explanation:

First we have to do whats in the parenthesis/ brackets, so lets rewrite the equation after we solve them.

(7)^2 - [4-9] + 2

We can simplify this even further

49 - [-5] + 2

54 + 2

Answer:

Q 12 roots of the equation

$2x^{2} -6+1=0 \\= (x-\frac{\sqrt{10} }{2})(x+\frac{\sqrt{10} }{2})\\$

∝ = $\frac{\sqrt{10} }{2}$

β = $-\frac{\sqrt{10} }{2}$

no matter if u oppose the root

(i) 2( $\frac{\sqrt{10} }{2}$ ) $(-\frac{\sqrt{10} }{2} )^{2}$ +2 $(\frac{\sqrt{10} }{2} )^{2}$ ( $-\frac{\sqrt{10} }{2}$ )+2(

(ii)( $(\frac{\sqrt{10} }{2})^{2}$ - 3 ( $\frac{\sqrt{10} }{2}$ )( $-\frac{\sqrt{10} }{2}$ ) + ( $(-\frac{\sqrt{10} }{2})^{2}$ ) = $\frac{25}{2}$

Q 13 roots of equation

$4x^{2} -3x-4=0\\\alpha = -0.693\\\beta = 1.443$

the roots of the second equation are

x1 = 1/3(-0.693) = -0.231

x2 = 1/3(1.443) = 0.481

the equation is

(x+0.231)(x-0.481)=0

$x^{2}-\frac{1}{4} x-\frac{1}{9}$
