Answer»

x-4 and x+1 x-5 and x-3x+5/5 and x-7/5 x+21/3 and x-2/3 is the correct ans pls

x-4 and x+1x-5 and x-3x+5/5 and x-7/5x+21/3 and x-2/3.please like my answer

x-4 and x+1x-5 and x-3x+5/5 and x-7/5x+21/3 and x-2/3.is the correct answer

x^2-3x-4= x^2-(4-1)x-4=x^2-4x+x-4=x(x-4)+1(x-4)=(x-4)(x-1)

4) x^2-8x+15 = x^2-5x-3x+15=x(x-5)-3(x-5)=(x-5)(x-3)7)7x^2-2x-5=7x^2-7x+5x-5=7x(x-1)+5(x-1)=(x-1)(7x+5)

(1) x,^2-3x-4=x^2-4x+x-4=x( x-4)+1(x-4) ={ x-4)( X+1); X=-4, 1; (4)x^2-8x+15=x^2-5x-3x+15= X( x-5)+3( x,-5)= ( X+3)(x-5); x,=3; -5!! (7)7x^2-2x-5=7x^2+5x-7x-5=X(7x+5)+1( 7x+5)= (7x+5)(x-1); ,x,=1, X=-5/7
