8(x+2)-4x+7 = 0
8x+16-4x+7 = 0
4x+23 = 0
x = -23/4
8x+16-4x+7 = 0
4x+23 = 0
x = -23/4
Please Simplify 8(x+2)-4x+7
8(x+2)-4x+7=8x+16-4x+7
=4x+23
x=-23/4.
=4x+23
x=-23/4.
Please simplify x^2+8x+7
I am taking it from your statement.
8x+16-4x+7=0
4x+23=0
4x=-23
x=-23/4
8x+16-4x+7=0
4x+23=0
4x=-23
x=-23/4
Simply by factorisation
X^2+7x+x+7= x(x+7)+1(x+7)= (x+1)(x+7)
putting this equal to zero we get solution for x as -1 or -7 ( if you are asked to solve it further asa quadratic equation)
X^2+7x+x+7= x(x+7)+1(x+7)= (x+1)(x+7)
putting this equal to zero we get solution for x as -1 or -7 ( if you are asked to solve it further asa quadratic equation)
8(x+2)-4x+7 = 0, i.e 8x+ 10-4x +7 = 8x-4x = -17, ie. 4x = 17, then x = 17/4 = 4.25
