You can put this solution on YOUR website!
(4x + 3)^2 = 5
16X^2+24X+9=5
16X^2+24X+9-5=0
16X^2+24X+4=0
4(4X^2+6X+1)=0
x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+
X=(-6+-SQRT[6^2-4*4*1])/2*4
X=(-6+-SQRT[36-16])/8
X=(-6+-SQRT20)/8
X=(-6+-4.472)/8
X=(-6+4.472)/8
X=-1.528/8
X=-.191 ANS.
X=(-6-4.472)/8
X=(-10.472)/8
X=-1.309
