(X-5)^2=7
X^2-10X+25=7
X^2-10X+25-7=0
X^2-10X+18=0 USING THE QUADRATIC EQUATION: x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+
X=(10+-SQRT[-10^2-4*1*18])/2*1
X=(10+-SQRT[100-72])/2
X=(10+-SQRT28)/2
X=(10+-5.29)/2
X=(10+5.29)/2
X=15.29/2
X=7.6458 ANSWER.
X=(10-5.29)/2
X=4.71/2
X=2.35 ANSWER.
