In a right triangle given sides are b=1 , c= root 10 ,a=? a= root { 1^2 +(root 10)^2 } = square root of 11 Because 1^2=1 & root 10^2=10
p(x)=2x-2 give different values for x and find p(X).Then x =domain,& p(X)=co domain example if x=1`,then p(X)=2.1 -2=0 x=2. thenP(X)=2.2-2= 2 in this case is domain is 1,2 codomain is 0,2 that is 1 mapped to zero 2 mapped to 2 hope it is clear?
x^2+8x+12=0 split middle term as X^2+6X+2X=12=0 ----- ----- taking out common factor X(X+6) + 2(X+6) (x+6) (x+2)=0 X=-6;-2
y=mx+b first line is y=8x-7 second line is y=2x-7 as m is not same ,that is slope is not same ,lines are not parrellel
X^2+5aX+6a^2 splitting the middle term as X^2+3ax+2aX+6ax^2 ------ --------- take common factor from 2 terms,sequentially as X(X+3a)+2a(X+3a) (X+2a) (X+3a) answer is x=-2a ;X=-3a Question 2: a^2+a-20=0 a^2+5a-4a-20=0 a(a+5)-4(a+5) (a+5) (a-4)=0 or a=-5 ;
